heres correct order for 454 IAC wireing - Third Generation F-Body Message Boards

Reds ttype · 12-17-2004, 11:48 PM

on the flat 4 IAC connector for a 454 tb it goes as follows

A green / black stripe
B green / white stripe
C blue / black stripe
D blue / white stripe

I post this because I searched on here for it and I kept seeing the opposite of what I posted so even tho the plug I cut off a junk truck had the color code I posted I wired it up backwards like I read on here and it wouldnt Idle for crap

I switched them around to the order above which is the original order on the plug I have and It works perfect

hope this helps some that are fighting Idle problems with 454 tb's

I believe turbo city makes a simple plug and play adapter.
