not sure if this is in the right section but here goes. So I'm swapping a vehicle frame using a 2008 awd escalade and its wiring (bcm/pcm/steering column/pedal assembly) it has a e38. I have hptuners pro. and I've ls swapped about 10 cars gen iii usually with 0411's and manuals or non elec autos. this is a new ball park for me. I have an android tablet ill probably use the obd2 for gauges. I'm just trying to figure out what the most cost effective options are given what I'm doing so everything works like it should. School me on what I would need to know about CAN bus so I can make sure I don't have something not working that should . Thanks
