HD Headlight Harnesses w/ 4 High Mod

[FellBeast]

There's a guy I've bought parts from in Kentucky who is in the southern IN and northern KY junkyards regularly. From stories he's told me, he's pulled a number of wiring harnesses to do swaps for his own trucks and for those of others.

Give him a PM at @murphy455 if you want, I'm sure he'll ship.

This is great! Thank you!

The rear lamps are connected to the same rear harness, PN 15302425.

You will pay an arm and a leg for New-Old-Stock, but if you have a Pick-and-Pull nearby, you can pull one (carefully) off pretty much any GMT400, and it isn't too difficult to remove.

The harness going from the back of the engine bay (C103 and C104) to the rear harness (C409) goes by many part numbers, mainly due to length and engine differences.
That one can be found at Pick-and-Pulls even more often than the rear harness. They are harder to pull and you may need to drop the tank to get it out (you have to on a suburban).


Neither are like the harness for the front lamps. I am in search of one off a late model, but those get cut off almost immediately when a donor show up on the yard.
They either get ripped off with the grill when some is after the radiator, or when then lamp housings get yanked.

Thank you for the info, but specifically that picture!

Helps me explain a LOT of what I am finding (albeit in pieces...).

Out of curiosity, what does C409/C407 plug into?

Thanks again!

C407 goes to the Plate Lamps.
C409 goes to the intermediate harness. (Photo from a harness I pulled from a petrol Suburban IIRC, had to drop the big tank to get it).

The intermediate harness connects to to C103, C104 (Rear of the Engine Bay), C409 (Bumper), and C114(?) (in front of the tank).

Connector End views, C103, C104, and C114 pulled from 99 SM, C409 was pulled from a 2002 carryover on acdelcotds

This is brilliant!

"Plate lamp" NEVER even entered my thoughts. Haha

Thanks again!
