I tried to plug in a power FC ECU today, into 98 car, with a conversion harness I've bought. It appears the harness is the wrong way round. Is it possible? Why would they have made it for an OBD2A ECU (can't be mapped) ->OBD1 car All the conversion harnesses I look at are the same, 3 rows in the sockets and 2 rows in the plugs, which I have, and need the opposite, hopefully the pictures can help explain.
