Does anyone have the wiring diagram for my 90 740 turbo that you could send me email? I can not find one local and have to fix my girlfriends car quick (if you know what I mean) I need the color codes fo the ign control unit and the engine control unit it is the LH2.4 The wires going to the knock sensor are grn and one black and the wires going to the tps are 2org,one wht and red, one blk. if this helps. I'm in a bind I'm getting code 3-1-2 and 2-1-3 and need to check the control units and make sure I'm following the corrct wires. Hurry thanks this is a 2.3
