This has been covered many times before. And yes you should have posted it the the eng management forum or better yet use the search function.
Anyway you need to bridge the 1E violet wire to the 1L yellow/black wire on the factory yellow plug left un plugged under the dash where the factory ECU use to be. Looking into the back of the plug with the locking tab facing up the violet wire would be the third one from the right on the top row and the yellow/black wire would be the sixth one from the right on the bottom row. Please note this plug is not from the engine harness but is from the body harness that plugs into the factory ECU. It should be still in place as long as someone did not get happy with a wire cutter.
The A/C switch sends a negative/ground signal via the violet wire to the ECU where depending on operating conditions the ECU sends a negative/ground signal via the yellow/black wire to the A/C relay so by bridging these two wires you by-pass the factory ECU form the A/C.
Also some aftermarket ECU's would use these same wires to control the A/C depending on conditions set to do so.
