yeah, that looks like it would work, also.

Can you check this in your wiring diagram? (or post the diagram you have and I can check it)

I'll look when i get to my home pc, but yeah, i think you should ahead and connect them... but since you need to re-pin the male end, you should be ok (the male end you have will end up with 2 wires coming from each pin, (if you ordered the ammount of pins that i posted, you should be fine)

hmmm crap..

the male pin should be 12084449

but mouser sells them in lots of 25,000


this is a road block.... i think i was envisioning all of the pins being present in the male connector, and just splicing to the wires, i guess. grrrrrrrr


there are other places on the web that have delpi parts, but will have to dig around some more.

alright, more info, man

part number
12040902

mouser is out of stock on these, but i think this particular number is a good GM number, too, so you might call your local dealer and ask about this p/n.

only place i find them online is here, in 10 packs.

"GM Micro-Pack: 12040902 Ga. 22 Tin Plated, 10/pcs": Sherco Auto Supply

tho, they're the 22AWG size, was hoping for larger.

I looked at this one too, and thought it would work, until i looked at it's drawing.

it's meant for a different connector body... wont work...

what you may end up doing is using the smaller pins, and just put one wire in there, and come out, and use solder/heat shrink to make your joint outside of the connector.....

no problem. I'd venture to guess that the ipod adapter one has all the pins in it, i know the similar one that is in my truck has all the pins, as it's a T-harness

I'm still ordering the pins I need to redo it completely and when installing my HUD yesterday, I found another connector that if I repin it, I can use a stock wiring harness.

what harness did you find?

x2... connector end views help alot, they have the delphi/gm p/n on them. post up in a thread what you're lookin for.
