Re: ECU swap: OBD2 for OBD1?
The OBDI- harness is comprised of 4 seperate plugs. The OBDII harness is one single plug... There must be a jumper harness made.
Rob, yes you would need to jump back to OBDII ECU's for inspection considering most scan the ECU through the diagnostic ports... Which will not be functioning w/ an OBDI ECU
