Ok so I have a 87 turbo II with a cosmo 13b-re with fc front cover contolled by a microtech lt10 all the original wiring harness was pulled out to make the engine bay look clean n run all new microtech wire harness I have all stock fc a/c components Im about to get my car back from my tuner this week and am wondering how I would go about wiring up my a/c? All the help I can get would be awsome

 

Anyone any ideas?

 

Have you looked in the FSM's Wiring Diagram Section? It fleshes out how the A/C is wired up in a stock car. The main thing is that with a standalone, you'll need to have the A/C Subharness, the one with FAC-01 and FAC-02.

How do you intend to do things regarding the A/C fan relays? All of my relays are integrated into a single fuse/relay box

 

Honestly I have no idea I got a 13b-re installed with a single turbo set up and the microtech all at the same time then ran across a complete a/c unit n wanted to kno step by step on how to get my a/c opperational via microtech Im in Florida a/c is a must

 

I think what Akagis is getting at is to look at the Factory setup and then adapt it to your car.
Since the Engine is a bit different there may be a little tweaking that needs to be done and since it is a custom job there won't be any true answer readily available.
Especially in the NEW Member Tech Section.
You may want to expand your inquiries to the 3rd gen Section.Also ask in the Microtech ECU section on how to control the AC.

 

As I recall, the AC only ties to the ECU in one way: the A/C request line. I am unsure if the A/C compressor signal is controlled by the ECU or just informs the ECU that the A/C is on.

Regardless, the A/C is independent from the Microtech. Frankly the Microtech is too stupid to do anything with the A/C.

You'd just need to bypass the stock wiring through the ECU and connect the output of the logicon directly to the compressor (it goes through the trinary switch in series). Wiring diagrams are in the Haynes or FSM.
