I replaced the lean burn slant six in my '84 D100 with a 440 more than thirty years ago. The wiring of the engine harness has become brittle over time. Of course the harness is no longer produced. Does anyone know where I might find a decent used harness. My guess would be any old harness has the same problems as mine. Any suggestions on what to do?
So your 84 harness has already been modified for a big block. If your bulkhead is good then just buy wire and make a new one. Its the engine harness so there is only about 8 wires.
