Hey Guys I recently put a 1995 engine in a 1992 q45.I had to adapt the plug for the cas because they are drastically different and will not interchange the heads where they mount are even different.I removed the cas and left it wired while turning it by hand,i expected if everything was right to hear injectors clicking there was nothing.I checked with a voltmeter and there is no voltage flash on the outputs to the computer.I had almost decided that I would have to find a 1995 ecu to match the engine,but when I checked it seems all 90 to 95s use the same ecu Is this possible?Short of an ecu I am about out of ideas.My old cas has 1 female connector and 1 male connector.My new cas is much smaller and has only one 5 pin connector.Does anyone have any ideas?

You must redesign the harness to fit the connector.........Create an adapter that plugs into 95 CAS and then matches the 2 circuits of the 92 harness.
