Re: 5.3 swap/tbi wiring
looks like you have a nice truck there. For wires from the truck, you pretty much only need a key-on power and the purple starter wire. If you were asking about converting the engine harness check www.lt1swap.com

Re: 5.3 swap/tbi wiring
Gut everything from the TBI ECM and wiring harness. Start clean from your truck to the new harness. You will need constant hot, keyed hot, and the starter wire
