you can fix these issues for about 20 bucks and a trip to a salvage yard and harbor freight for marine grade shrink tube 6 inches of solder and water proof fuse holders

Thanks for the review. I brought from you guys on my last swap and will do so for my new project. I chose quality over crap! I don’t need the headache

Nice work, keep them coming! 📹

I purchased your harness based off of your reputation and solid attention to detail. I'm not risking the need for troubleshooting on a first start up. I feel you get what you pay for and I didn't want to cheap out on something I only want to install once. Thanks for offering this information and being an honest, affordable, American built company. Thank you for your service! I didn't feel it was nit picking, if you are in the Industry, you know the standards. Sure tape works for the time being, but I couldn't imagine having to troubleshoot random problems once corrosion gets in there. I look forward to installing your harness.

Well, now you know you need to up your game and reduce your prices to stay competitive.

I've watched a number of videos on LS wiring harnesses and glad I ran across this video. I've looked at your site and looks like there are a number of options in the $500-$600. I will gladly pay the price difference to have something made by somebody that I can communicate with if I have a problem. If I need to save money on my LS swap, I'll save money somehwere other than the wiring harness.

This video would lead you to believe anyone that's ever used one of these harnesses is already dead. I get the feeling he's got some incentive to make the smaller issues seem life threatening... idk.

:) glad I built my own then lol. Thank you for showing this. I did a stint modifying factory harnesses for guys that bitched about costs constantly. I no longer do so not worth the hassle lol

I have one of your harnesses in my Lt swapped 67 c10. My hot starter post is very close to my SE long tube headers. Are you saying your harness is fused protected should my header somehow come in contact with my starter post?? This keeps me up at night, lol. Thanks for your attention to detail and excellent quality, almost 7,000 miles and zero issues.

Grate for testing harness

Thanks for the info

Does your harness make my 1992 C1500 gauges work? Im swapping it with an gen 3 LS1. If so how much for it ?

Good video very professional ..

I ordered one of these harnesses (looked exactly like this one) and was getting a crank/no start condition. After combing through all the possibilities, I decided to check out all the pin out connections to the pcm. To my surprise it was pinned wrong. The knock sensor pins were switch with the crankshaft position sensor pin slots. After I found this I removed the whole harness and am waiting on a quality American made on e now.

I am in the process of doing a LS swap in my hot rod project. I am glad that I found your video before I ordered a LS swap harness. Thank you for doing this video and saving many of us from wasting good money on a junk harness. Buy American and do it right the first time! I will be calling you guys for my wiring harness. Just subscribed to your website too!

I just bought one of you guys harness. Bought that harness having same issue trans not shifting

I have installed quite a few of your harnesses on customers vehicle's and have had nothing but good luck out of them. Out of the probably 15 of your harnesses I have installed I have had one issue and it was a ground wire that had pulled out which could've very well been caused by me while pulling it through the firewall. I have used two gen IV harnesses from PSI that were bought by the client both of which I have had issues out of where I had to stay on the phone for about 2 hours with their tech line trying to get the bugs worked out. Not to mention their tech line guys weren't the most personable people. Just today a friend of mine got this exact harness directly from HPI's website and honestly me being a wiring guy I didn't even feel comfortable touching it or installing it. I wouldve been more confident installing one that someone made in their garage than using this thing. Their website even went to the extent of saying that it's made it the US and is OEM color coded and it very obviously is not.

This harness not only looks identical to the PSI harness I reviewed earlier this year, but also has a lot of the same issues and the same paperwork and color coding. I’m sure thats not a coincidence. I believe they have been outsourcing for sometime and the China manufacturer they were outsourcing to is now selling their harnesses for 1/3 the price. Happens all the time and it’s a chance you take when outsourcing to countries where you can’t protect your products. Just my personal theory after using one of their harnesses and seeing several of these reviewed online now.

Thanks for the info 👍

Love the video as I'm throwing an "hpi" harness in the scrap pile. Cane with car, I already know better. But then I found this video to share! Problem I have with this video, no mention of the non txl jacket wire. Everything about these harnesses is garbage!

That's why I'm going to rework a factory harness for my swap. I'm sure you guys build excellent harnesses but I'm cheap.

Man leave that harness alone and send it to me

This video is nitpicking at it finest. But I did learn a few things to do when I get my Chinese harness. Open bank 1 and 2 and solder the fuel injector wires and shrink wrap them. Remove the starter and battery wires and replace them with a larger guage wire and add fusible links. Add some silicone to the back of the ECM connectors and the grommet that goes through the firewall. Let's not act like people redoing these harnesses themselves for their projects aren't doing way worse the ln what's in this video.

Funny all the China hate comments. Probably send from their iPhone made in China.😂 Personally i know for a fact as a consumer that in fact there are lousy copys of certain products. But, a lot of stuff is made in China, shipped to the usa, and those who don't read the package think they buy a usa made product. What about the shirts, pants, shoes, whatever made in Pakistan, Bangladesh, poland etc?.. I just bought a wiring harness for a 67 truck. On Aliexpress . Payed a third of the normal 600 dollar painless wiring pricetag. Compared it and it was identical. So who knows this wiring harness is made in China and shipped overseas? Bought some "american" suspension parts at Rockauto. Items where shipped separate from different "wharehouses" wich where: China, Mexico and Tsjech. So what did i believe to buy? An american product? You tell me! Billet aluminium valve covers from Holley. Big pricetag!! Ready to order but did some fitment research through Google. Stumbled upon the same pics..... Huh, Aliexpress. Compared the two. Excactly the same pics! And the Ali items where half the price and shipped from Tsjech(again) Same with an aluminium radiator from Summit... For me as an european these items, also shipped from China or europe are waaay cheaper. So, again, tell me whats fake, whats not, whats "european/us made" and what is copied or outsourced?.....

Moisture in the conectors?!. Most guys are trying to hide them in the cab.

Do the two battery cable cause a parasitic draw ?

Min cam with the bolts but no oil plug

i have ran china harness on several LS swaps and have had (zero) issues and 2 of my swaps have been on the road running everyday, maybe lower your price for the working man will help????????????

I'm a diesel mechanic and work at 2 different dealership and all the packages that have the engine, chassis, and transmission harness come from China. Plus if it was unsafe, the U.S or DOT will put a banned on it.

How does the consumer know if your harness's aren't made in china and then resold for a major profit (I get yall gotta eat too, but not trying to go broke in the process, for $500 more I can do the Holley EFI setup? After viewing your site and just glancing at the red and blue connectors it appears to be the same to me.. Furthermore your harness for for DBC-T56 didn't list if the fans were added or not. Thanks in advance, yes im debating with myself weather to purchase yours or theirs..

What about speartech and psi??

Its like everything ....i use to work at a furniture store and owner has Chinese friend that can fabricate anything you take them from the united states and they open it up and duplicate the product but with cheaper material and when i say anything i mean anything their engineer was 2? Years old and can take apart anything and reconstructed it with their technology but in the least expensive way to save money .....

you're actually being very nitpicky with this harness. Honda oem doesn't use fusible links and also uses crimps and tapes on splices like that. i personally have never had any issues with my car and there's millions of older hondas still on the road

the factory gm harness used duct tape over splices...at least in 2010

"el cheapo tape" struggles to take off starts heavy breathing

some of you all,need to realise,that the harnesses are coming out of One factory...& some of you need to reconcile that Cheap is Not Good....And Good is Not Cheap.

I must admit I bought another ls harness from ebay and I am having trouble with injector plugs not grounding. My luck has ran out. Lol

Why do I need a harness from anywhere, my cars all have harnesses from the factory.

That's a psi harness had a few

So buy china and redo the harness if you’re handy the right way. Check

I’m not arguing for or against these knockoff Chinese copies (harnesses, heads, springs etc...) but the people buying them generally can’t afford the “real” US made stuff. And unfortunately as time progresses the Chinese copies start out crappy but if enough people buy them the quality improves while the price remains low. Sometime after like 2004 the Chinese turbos started popping up on eBay (that’s when I remember first seeing these) and initially they were shit and would blow very quickly, but after a few years as Tony Angelo said “the 8 year olds in China have stepped up their game and these things actually work”, so American companies that make these aftermarket parts need to make things with more attractive prices to compete with the copies. I’m not saying not to have the bucks up expensive parts but you guys need budget lines. A basic harness for $150-$200 should be plenty doable (I’ve made custom harnesses so I know what goes into them) otherwise in a few years there won’t be a reason not to buy the copies aside from them being made in a communist country that uses slave labor but when did that ever stop people from buying something

Just received my chins harness for $190 , came with the pcm bolt…9/10 people buying the cheap harnesses aren’t building show room cars and don’t care wether or not their cars blow up. I do appreciate the info for when I go to install my cheap harness. It’ll work for me until I can afford to spend $500-$600 on a harness.

I believe you do make a quality product however I think there are several different manufacturers making these but they're not all the same quality. I got one that was 240 something dollars and all the stuff that you listed up there either they watched your video and they fixed it or I just have a lot better quality made Chinese. All my connectors are heat shrunk the wire gauge seems to be a little better and they're splicing is also heat shrunk. My instruction manual is also better and mine came with the bolt. Lol. Thanks for the review 👍

It’s still insane that people want $650 for one hour harness build it from the old harness

a the camera ur using is from china so this means what

So i decided to purchase one of these china harnesses..Very bad idea.. trans wouldn't shift . It was pinned wrong. Trans was pinned to injector and what injectors that where pinned where crossed..

Listen to this man. I have worked with GM harnesses for years. GM has many hours of R&D invested in the latest terminals and seals. I can verify that aftermarket and China terminals and connectors will not compete with GM components. BP Automotive has the best equipment for harness manufacture. If you want years of trouble-free service, pay the money and get top quality.

Cheap guy here.... Take my money

Imagine a harness company talking down on a different one. If yalls wasn't twice or three times the cost, wouldn't be an issue.
