EG hatch - Where do I connect these A/C wires?
hi guys,
my eg hatch has a new engine d15b and my a/c system is using the old lines, have obd1harness with p28c52 ecu, only to find out that A15 ang B5 was cut and wasn't connected to any wires. my question is where should i connect these two wires to make my a/c working again. by the way my a/c is running before but was using this toyota idle up to bring the idle when it goes down. but these stuffs plus the wires are pain in the *** to see it everyday. is this still possible?
pls help

ECU A15 is a black/red wire that is connected to pin 4 on the a/c clutch relay.
B5 is a blue/red wire that connects to pin 1 at the a/c pressure switch.

Hmmmm. I wonder how the A/C was working if ECUs A/C clutch relay control lead was not connected????
Need more info on how this A/C system was wired before. 94

my a/c was working before but i was using this idle up by toyota to compensate the idle when it goes down. i will take a pic of my relays as i see in there a side by side relays and not sure though w/c is the ac clutch relay though i can see a blk/red on the other and blue/red on the other one. as per above diagram i guess i have an idea. thanks for the replies i'll post the pics once got them.
