hey i need help on an problem that i ran into . I have an 90 body fc and i just recently just bough that i cant t an 88 engine now i cant run the harness from an 88 to 90 . I found out that i can go by just download the factory service manuals for each year, finding the electrical pin-out diagrams, and connect the right wires and Make sure that i do some research on the TPS - they are different between those two years and removed the stock ECU and installed a Megasquirt..or something similar. What can i do to get this engine start up right away .
