1992 Coupe IAC wiring question
I have a 1992 Coupe, 6 speed. I recently replaced the IAC Pigtail because the connector crumbled when I took it off.
It runs great except when it gets to about 150 degrees it acts like it wants to stall out, but doesnt. Then after warm up it runs great again.
I looked at the IAC in the Elec Supplement (Vin "P") and it shows wires :
A= Light Blue/White
B= Light Blue/Black
C= Light Green/White
D= Light Green/Black
Here's the problem: My actual wiring harness has:
A=Light Green/White Stripe
B=Light Green/Black stripe
C=Light Green/Black Stripe
D=Light Green/White stripe
Now I'm stuck wondering if I have an early or late model, or if the Electrical Schematic is wrong? Is this a common problem?
How can I double check this? Any help would be appreciated.

It's very difficult to believe you've multiples of the same colors at the same connector.
'93 is mentioned to be the same as what you first mention and I believe even L98 IAC wires were colored and pinned similarly. FADED BLUE to GREEN maybe? Dig deeper into the conduit. SQUINT?

Never mind and thanks for the reply.... The original harness wires were very faded...I was able to sort it out. They were kind of a Grayish green, so I figured those were were the Blue wires.
