i know this sounds silly after doing a whole ls1 swap. i am finishing up my wiring and i need to hook 12v ign to my fuse block. i see that it's a pink and black wire but it doesn't seem a heavy enough guage? connector 207 has one free and was thinking of picking up that wire but there is a thick pink wire on c100 and was wondering if this one is 12v ign? it's for a 1989 iroc. thanks for any help.

 

i just found a good diagram on austin third gen. it looks like i can use the pink wire f4 on c100.

 

The heavy pink wire in the C100 was IGN to your coil and will be the main source of IGN for your whole harness. I dont know of one large enough to support all of the electronics aside from that one

 

sounds like the best bet would be to use this to trigger a relay from the battery to run everything else. unlimited juice there

 

BINGO!

You wanna run that thick pink wire to a good relay, and use straight battery power to run all the electrics. Best way to fly.
