    Default 112-588 Throttle Body

    I was using a stock style LT1 (90° sheet version) throttle body, and I'm switching to the 4150 style. I noticed the paperwork for the new throttle body, says the IAC is a Chrysler style and must be pinned as such. I had to replace the square TPI IAC connector and replace it with the flat 4 pin later model GM one for the LT2 throttle body IAC. I can't seem to locate the wire color/pin location information to make sure they are the same, anyone have any idea? Thanks in advance!
