Hi guys. Found this site after extensively searching the web on TBI swaps and it seems like a great source of info. I am in the process of converting a friends 59 Chevy Apache pickup from a straight 6 to 350 TBI out of an 88 Chevy 2wd pickup. We are using the donor rigs wiring harness. Anyway, I have the mounts fabbed and engine in and and getting close to trying to wire it up. We stripped the harness and all sensors from the donor but the part I am having trouble understanding is what exactly I need to power up for wires from the harness? I plan to add a 6 lug fuse block just for this purpose. I have some wiring diagrams that are helpful, but don't know what wires I NEED hooked to the fuse block, or elsewhere? We are using the 5 speed manual from donor as well and since we are using the stock wiring do I need to do anything to work the VSS? . For a gas tank we were thinking of an 88 Blazer which dimensionally looks doable, and takes the same pump/wiring etc..

Thanks for your time,
Chad
