Sorry, I didn't do a tutorial video on the wiring harness. I thought about it but felt it may have been too involved. With the plug at the front bumper, a guy could run up to 4 wires to the fuse box. So depending on the project, a custom harness could be made. The parts needed would be the appropriate connectors at the front bumper, 18 gauge multi-stranded copper wire, wire sheath of some sort, grounding loop connector, and pins for the fuse box.

The Subaru emblem does not light up. I did think about adding one or a lit up STi badge. I may do this at a later date. I could tap right into the DRL power wire.

Depending on the year of STi you've got. For all the VA chassis WRX or STi's, the interior wires are all there. So, you will just need the fog light switch and the relay. The biggest difference is in the engine bay itself. Some models have the fog light wires ran to the engine bay relay box and others do not. I can say the 2020-2021 do not have the engine bay wires. You will need to run them yourself. Everything I have mentioned is if you want that OEM setup. There are outfits out there like Diode Dynamics that do have kits for a plug-n-play type setup. You just run their kit in your car.

@@wsucougarx i have a 2021 sti. Nice to know that I just need to buy the foglight switch and the wires like u have in the video. I kinda want OEM like yours but I'd rather have the plug and play and not worry abt the wirings anymore.

There was no kit per say. I sourced all the parts individually from JapanPart.com, Subaru dealerships, and various online Subaru parts places.
