hey anyone out there...im swapping a d16z6 engine into my 89 rex dx....i want to convert to obd1 with out using a resistor box or anything....but the problem that im having right now is tracking the wires for the dx engine harness from the main plugs...because what i had in mind was to cut the plugs off the main fire wall harness and just weld the old one onto the newer motor engine harness...any body know what these wires are....the one at the passenger side and the driver side...( the main fire wall plugs...for the dx engine harness...)please help someone...i know someone knows the wires...i got the manual and actual honda manuals. but they arent complete...
