TC 5.0 swapped, Hello A/C!!!!!

To those of you that have done the swap, what has to be done to make the a/c work? I've been digging through diagrams and still no luck. Help!!!!!

I'm guessing not since I had to repin most connections going into the dash harness.  The A/C is the only part I'm having trouble with.

It's down to this wire and finding where it gets its signal. It's the positive feed for the low pressure switch. The colors are light green with purple stripe. If I power this wire the compressor kicks on. BTW ice cold air is my favorite!

From the 88 EVTM:
C232 Gray 8 pin connector.
C344 Black 4 pin connecter

It depends on the year of the TC. 87-88 uses the IRCM for then clutch circuit relay. Post Year to continue!! Or power that wire up to the dash control circuit that controls the clutch in the dash. By the way you have to get it after the CCOT switch. Reason being you do not want to ice up the evaporator if you get a low charge.

I am guessing the IRCM went away with the 2.3.
That leaves you without an WOT AC cutout.
You also lost the feed back to the EEC pin 10 to tell the EEC that the AC clutch is engaged.
Do want to put either of those back in?

Is the cable from the dash control, that I circled, still there or was it pulled out?

I didn't mean to use the IRCM.
I mean to do the WOT cutout and EEC pin 10 the way it is done on the 5.0.

Here's what I found in the archives.

GreenPuple-A/C low pressure cut out switch(this one's tricky,the original a/c compressor was on the pass side(5.0drs side) so stranglely enough you will find the car's greenpurple wire in a grey 4 pin connector near the pass headlamp assy.What i did here was cut the green/purple at the switch and soldered in a new wire and ran it down the pass side to the grey 4 pin,then i stole the connector from my 4 banger harness and inserted the pin and soldered it.

If the WOT is the relay on the passenger strut tower, then I haven't messed with that quite yet but it is hooked up.

This is C344 that I circled in the diagram I posted.

So, does this mean you can turn on the AC with the dash control?

The IRCM is on the front side of the strut tower.
I am more than a little confused here. Are you using the IRCM or did you install an EEC power relay? Does the car run?

I can turn on the A/C by powering the light green/purple wire.  The EATC does not control the a/c clutch like it should.
