I have been asked to look at a JDM swap someone purchased to put in their 93 delsol. It is a obd1 GSR swap, automatic. The Auto p72 ecu is not like your regular 3 plug ecu, this one has 4. The 4th being the internal TCM (tranny control modual). After searching for wiring on this, I have learned that this style ecu only came on obd1 JDM automatic gsr's, civics and preludes, therefore, there is not much info out there on them. I was wondering if anyone has come across this, and know/ have a wiring diagram for it. It is a 12 pin plug, with 4 wires out to the strut tower plug, and 8 wires that go into the dash somewhere (these 8 were cut). The JDM harness is partially hacked, but I can trace 4 of the 12 wires to two sensors on the side of the tranny case, the shift solinoids are where they normally are ontop of the tranny and wiring is the same for them.

All other pinouts seem to be in their normal places, its just the TCM that is causing greif.

Any help would be appreshiated.
