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

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

Hoping someone could point on the firewall with a pix

Are you using the original firewall plug to make the passage thru the firewall?

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 · 03-12-2019, 12:31 PM

still having trouble with this American Autowire kit. any experience with the wiring i described.?

MOJO1963GMC · 03-12-2019, 04:39 PM

tag. Is this the same for the '63s? GREAT firewall pic

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

Afirehawk1 · 03-18-2019, 03:08 PM

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