Connect diag connector from S4 harness to S5 ECU

[jimmydanny]

Anyone know how I hack this up so I can get some blinks out of that :censored::censored::censored::censored:? Nothing is connected atm, so I am starting with a blank page so to speak.

Just got a new front harness plug to the ECU, the wires are different colors from the previous plug, so I guess the new plug is S5, while the harness itself is S4 of course, as my car is.

I do NOT have the engine check light, meaning I have to use the JDM/S4 way of checking my codes with two light bulbs or leds and one ground wire (or opposite, anyways).

As for my problem, the timing is right, I get spark, fuel, air, but I get backfire all the time and it runs like a pile of :censored::censored::censored::censored:, a big pile of it too.

TPS\' are adjusted properly, AFM works, MAP I haven\'t tested yet, the vacuum is pretty bad but I guess that is because I had to adjust the throttle valves to be more open as I don\'t have the BAC.

Cheers, Jim
