Hi all! I've got a heater control from a 2000 Astro (ACDELCO Part# 1572218) that I'm using to build out a custom car. I'm trying to find a source for the two electrical plugs that are on the back of the control. One has 8 pins (4 pins in two rows) and one has three pins (3 straight across). The three pin plug has a key so that it can only be plugged in one way. I don't need the whole wiring harness since I'm going to graft this into an already existing system. If I can get the plugs cut from a harness with enough pigtail to splice them, that would work fine. Does anyone know of a source for these?

All help is appreciated!

Cheers!
