A/C wiring??

I've read in some other posts that to get k-pro to control the a/c system I need to make 3 changes in the ecu and then connect the vtp (b9) to the acs

According to this schematic I need to connect b9 to a27. If I cut and connect these wires then the a/c system will work properly right?

Well I just tried it and it didn't work. The compressor clutch didn't come on. So I tried hooking up the acc wire (a17) to the same b9 and it worked. So with a17 and a27 both hooked up to b9 things seem to be okay.......Just a question though, by doing this am I bypassing the thermostat or pressure switch? Will by compressor cycle on and off?

You need to identify which vehicle each pin belongs to.

It should be Civic A17 to RSX E18 and Civic A27 to RSX B9

Well, like you say I guess I need to hook up the Civic A17 to RSX E18 and Civic A27 to RSX B9. The problem is is that the Hybrid-Racing Harness doesn't have a pin out for E18. I'm going to have to find a connector at Radio Shack or something to put in it's place I guess.

yes sir, I pulled a pin from a spare connector and added it to the hybrid harness. The A/c works great. Thumbs down to hybrid for not putting the pin in place......

I have a dc2 hybrid kit. you think I will have to do that also?
I wired up the relay already but my compressor always stays engaged, when I turn on my ac..

anyways how cold is your vent temps? my 89 si r12 blows about 40 degrees in about 98 degress. I haven't got my dc2 ac system completely charged yet.

I haven't charged mine that well either, so mine won't pull the temp down to 40 degrees yet.......I will have to check to see if the compressor will cycle after I fix that.
