I have already changed out the rear axle and upgraded the front end to handle the V8. I dropped in the engine yesterday and I have now begun to start the wiring issue, the only problem is I don't know where to start. The engine is a 302 H.O. from a Lincoln Mark VII, I know its speed density but the price was right and it included the transmission as well. I haven't touched any of the mustang original engine harness, nor have I modified the EFI harness. The new harness looks complete and unmolested. Any help would be greatly appreciated.
