Hello! New to group. I have a restored 93' Chevy 1500 with a 4.3 V6, and 4L60E trans. I recently bought what I thought was a 95 LT1. To my chagrin, it is a " baby LT" L99 4.3 V8. The wiring harness looked mostly complete with PCM. My confusion , just one of, is that the PCM says 94-95 B or F body LT1. Gonna be needing a lot of help on this as I am used to running a OBD1 TBI motor, and new to all this LT stuff. But that's why we do this stuff, it's a challenge. Possibly gonna need new harness, and most definitely a program for the OBD1 95 programmable PCM. Thanks for adding me to this group, as I do know Dynamic EFI is a reputable company.
