Are they all WIRED different? It's not often mentioned, but grey and green connectors almost all will plug right in regardless. The only one that I think is different is the igniter in some cases. I know I had a mismatched coil pack and I think also CPS in my old white car.

I am using a yellow plug harness on an 89 engine just because my car is a yellow plug chassis. On my gte, I had to re wire three or four sensors, but I know two of them were on the water neck side....ge only has one on the water neck to re-wire if I remember correctly. Luckily, I had an 89 harness lying around with all the needed connectors so I could just splice the connectors I needed onto the harness.
