Hi guys, I'm not having much luck finding info on this particular swap. I'm repowering my 98 3500 from a 360 gas to a 95 12 valve and I'm wondering if anyone else has any insight on the swap as far as wiring. I have the 95 engine harness with the ecm and I also have the headlight to dash harness for the 95 diesel which of course doesn't plug into the 98 dash harness. Would it be possible to wire the diesel ecm and engine harness into the 98 gas headlight to dash harness? What about swapping the connector from the 98 gas headlight to dash harness to the 95 diesel headlight to dash harness? Any ideas might help and would be much appreciated.
