Almost ready to start on an LQ9-turbo 400 89 notch.Don't have a harness yet just a 02 truck PCM 1220041.Motor is an 03 with DBW T-body.Should I go with a cable t-body instead?What harness do you think trying to do this on the cheap right now just to get it up and running

 

I would use a cable , pcm can be reflashed to cable OS, since you don't have a harness yet. early truck or camaro harness
