Yep ive been using this
Not sure still where these 2 wires go thru

**The Rocknrod** · 03-10-2019, 05:38 PM

Do you have a wiring diagram? It will show the plug, hence the size of the hole. - http://webhosting.web.com/imagelib/s...ng%20Schematic

Why is there a hole for the TAIL LIGHT WIRING in the firewall ??

Afirehawk1 · 03-12-2019, 04:51 PM

i think the brown "alternator ignition" wire goes to the alternator itself.
the small red paired with the solenoid purple goes to the dash harness.
yet i havent figured where thru the firewall it goes.

help

the rear tail light harness from the dash comes out this hole down the firewall and runs back to the rear of the truck.

If you are not using an hei then the white wire would go to the coil, the pink would eventually get there after it goes through the ballast resistor.

Worth mentioning I have never used this harness, I'm going off the diagram you posted.

Afirehawk1 · 03-18-2019, 03:08 PM

Ok i think i figured it out
Suggestions on where to get a 2 wire firewall grommet?
