Today we finally get a 6.86" Holley Pro Dash. We get it installed, wired up, and programmed for turn signals, hi beam indicator, and fuel gauge. We also discover the true purpose of pin 26 the sensor ground.

Wiring is probably the most painful part of the process. At least it is for me. Thanks for the insight!

I used to think so. Now, I find it fun to figure out different ways to do things or add newer parts to older cars. Glad it could help you!!

Sweet setup! Blowing my tax return on the Chevelle SS Dakota RTX series and a module for it to talk with Terminator X . Most overpriced item I’ve purchased for my budget build, but damn are they sexy!! Looking forward to more Chevelle updates from you!

Sounds nice. I almost went that way, but I liked how I can forever change the holley dash if I get bored. Stay tuned. There is tons more coming!!

Yes! You MUST use the sensor ground pin for your fuel gauge, or it won't read correct. I made that mistake also. I realized something was wrong with my fuel gauge when the automatic dimming of the display would brighten and dim down. The fuel gauge would also vary by about 1/4 of a tank. I then ran the fuel sender ground directly to the dash it was fixed. As far as ride height sensors, I used the Ford Expedition. Lincoln Navigator sensors from a You-Pull-It yard. Cost $7 each with the connectors. They are small, have built in bolt mount holes and use a ball joint type of connecting rod. The sensors have a short 3.5" total swing, so I lengthened the arm to get a total of 6" of suspension travel. 0-5 volts.

Can you do a viedo on the Holley pro dash tach hookup. My tach is not working.

when wiring up fuel level sensor , one wire goes to the pin 21 for input. does the other wire go to sensor ground on the dash input or chassis ground? thank you

The only way I could get my dash to read accurately was to ground to the sensor ground pin26 I think it was. Even then, it's still slightly off. Since that is a ground circuit, its path has to be from where your sending unit gets it's ground, and go to the holley sensor ground.

where exactly on the LS harness did you find those pins? im about to return the 5 pin/wire kit i ordered from holley lol

Any PCM pin will also slide into the pro dash connector. Just undo the lock tabs.

Question. I have the pro dash went away for a month so disconnected battery. Came back to connected battery car started right up but my pro dash just has the top lights light up then goes out and the screen is black / blank. Have you had these issues or no where I should look

@RecycledRacing Ай бұрын

Every once and a while mine will freeze the screen when driving, or fail to boot up. I just recycle the key and it's usually fine. Double check your connections as always.

@@RecycledRacing I’ve cycled it multiple times 20-30 times. Connections are all good and are all soldered. Mine use to not come on every 1 out of 6 times then cycled and it would be good. Now nothing and the only thing I did was disconnected the battery then reconnected 🤷‍♂️ my 3.5” screen works fine so I know it’s not the holley efi.
