I've swapped an 03 Truck 5.3 and 4L60E into my 81 Camaro, I have the wiring out (blue and Green PCM connectors) and am looking at the Pin out diagram here: http://lt1swap.com/2003-07pcmpinouts.pdf He has items listed in Yellow as "remove" and I am a little standoffish about it because 1.) I want to run AC ( he has all listed AC items removed) And 2.) I am concerned about what he has removed for the Fuel Pump. I have an 02ish LS1 Fuel Pump retrofitted in my stock 81 Tank. I have the black, gray, and purple pigtail for the pump and not the emission plug I feel like I'm getting a little complicated with laying this out and I would like to get answers, so I'll stop there for now..anyone that's done your own pin outs or programming have any input on what I want to do?
