A/C Amp to ECU Wireing

[Corona]

Hi All,

Ive been tring to get the A/C working on my car after the engine swap. I have it all wired up, except for the 2 wires that go to the ECU from the A/C Amp. I have had a look on the net for pin outs of the Old 3SFE and the only one that I can find is http://www.geocities.com/MotorCity/Pit/9975/enginepix/drawings/ToyTCCS_Pins_3S-FE_MAP.gif which is not the correct one for the ECU that came out of the car.
The Wires that I am trying to conect I belive are the ACT and ACA. I have the one for the Clutch sorted.
If nobody has a pinout, would it do any damage if I just took a 50/50 guess and hooked them up?

Thanks

Neil
