[V]

When i did a SD tpi swap into an 87 Monte ss, i bought a custom stand alone harness off ebay. the seller was very helpful even a few months later when i had questions. i only had to hook up power acc ground and then i used vdo gauges since the gauges run separate of the ecm (except vss). People over complicate wiring swaps imo. i love electrical wiring but then again i had started taking electrical engineering in college now im going for mechanical. There is one great website i used. i think it is like chevythunder .com or like that. It had info about all year tpis and what swapped or could be made to work.

oh and of course id be willing to come by and give a hand here and there depending on my schedule. i could also possibly draw up diagram and instructions as to what wires to connect or splice.
