Finally getting around to sorting out last seasons issues. When testing from +12 (yellow wire) I go straight to ground... Gotta obviously sort that out before I fry the ECU (if it's not already shot!). I've got the harness opened up pretty good, and in the process discovered many brown wires (engine ground?) going into ONE 18 gauge wire to ground... I'm guessing this should be 12gauge ish? Did find a skinned green/white wire to the timing sensor (though I'm not sure it was grounded because the harness was taped up pretty good) and a ground connection pulled apart so far.

Anyone have a diagram or know where I could get one that's legible? My cat manual doesn't have any.
