Originally I planned on running my MS standalone. I figured I could make it with out AC until someone figured out the AC circuit for the 96-97. The warmer weather is getting here, and I decided I can't wait. The thought of getting out of my car with *** sweat stains on my khakis at work is to much. I have decided to run my MS with the factory computer.

The problem is that onlinecomponents.com has PN:174514-6 on back order for 8 weeks. The only other place on Tyco's website doesn't appear to sell the volume I want to purchase. I was just curious if anyone had one available, and would be willing to part with it. Thanks

 

Are you looking for a 96 ECU? if that is the case pm me (I bought an extra one I'm not using).

 

Nevermind; I saw that you're looking for the boomslang.

 

Thanks for trying Rafa. I realize I wasn't exactly clear.

I'm actually just looking for the connector that is specific to the 96-97 cars for the boomslang. The 90-95 cars use two connectors that plug into the factory ECU according to Brain's howto, and the 96-97 cars use three connectors that plug into the factory ECU.

 

Although if someone has the complete harness for a 96-97 I would consider buying it for the right price.

 

I know that Chad made me a harness but I don't know if he has any time available now to make you one (he just started working).

 

At the ECU connector, splice the following wires together:

1: Green / Black at 1K (from the A/C switch and refrig. pressure safety switch)
2: Blue / Black at 1G (drives the A/C relay, which powers the clutch)
3: Blue / White at 1B (drives the condenser fan relay)
4: optional Black / Green at 1A (drives the cooling fan relay). Note, use a 1N400(x) diode to make this last splice, with the non-striped end facing 1A. Otherwise, every time the cooling fan comes on the A/C will come on.

 

Did I miss a thread some where?

Joe, should I blindly trust you or should I try to wrap my head around this?

 

I have a 96/97 MS parallel harness I am not using. $50?

 

I think you should buy Paul's but; fwiw, Joe knows his **** so, yes you can trust him blindly!

 

Joe definitely knows his stuff, but Paul has a PM. I might start messing with the AC stuff in the fall when things cool off.

 

What modifications would be needed to make this harness work with a '99? Or would I be better off building my own?
