I'm new to EFI conversions and I have a big project with hopes of finding help here. I have a 1986 Chevy4x4 that I'm swapping in a cadillac 500 motor and a 4L80E transmission. I am converting the 500 to TBI froma chevy 454. I have the throttle body and adapter. A brand new engine wiring harness for a 1992-1995chevy truck. Some of the sensors. A cadillac engine to chevy transmission adapter. The PCM I think I need is the 16197427 to control the tbi and transmission. I know there's more parts I need but it's a start.
Hope this site can help me with what to do and what I need. Thanks
