Thinking about transplanting a 1990 TBI engine and overdrive automatic into a 53. I hve the complete 90 model pickup for a doaner. Could the wiring harness from the 90 model be thined down and used for the swap. As for the fuel system I'm planning on building a between the frame rails tank and adapting the gm pump to that tank. I'm kind of new to the fuel injected stuff but willing to learn.
