I have an 1986, BUT my car has a 88 TC computer that has a 86 TC wiring harness thats been repinned for the LA3. I am now told that because my car does not have an IRCM (like the 88)which controls the cut off switch, I am in a pickle. Is there a way to jumper the wiring so under WOT the AC doesnt cut out?

From the 84 thru 87 EVTM's:
2.3 Turbo does not have a WOT A/C cutout relay.

On 3.8 and 5.0, EEC pin 54 provides the ground for for the WOT A/C cutout relay.

On 84 thru 86 2.3 Turbo, EEC pin 54 is not used.

On 87 Turbo, EEC pin 54 goes to the A/C clutch solenoid control in the IRCM.
