Terminator X Max and AC Ok try to make this short as possible. I have a 2000 5.3 LS rebuilt from ground up, all WS6 internals and was running PSI Wiring and since then have converted to the new holley Terminator X Max. All wired up, but i have my black wire form the AC to hook up and no idea where to hook this up in relation to Holley kit. I know there are the extra wires, Fan 1 & 2 - have those done, then there is the IAC Kick and AC Shutdown wire, i do not think the wire from my ac goes to the AC Kick Down and i have no idea what to do if anything with the IAC Kickdown wire. Any help is greatly appreciated!!

Thank you for taking the time to respond. I appologize for not being more specific. So I am working with a 1969 Chevy C10 Truck with the 2000 era 5.3 LS and 4L60E. I have the entire truck rebuilt and was running with the PSI Wiring harness, but i hate not knowing what is going on with the motor or being able to adjust things, so the Holley Terminator Max is the ticket i think. With that all said, i have the entire thing re-wired with the Holley kit and this is where i run into my questions or issues.
The AC is a Vintage Air kit and was working with the PSI wiring installed. The wire i was asking about is the black wire, which if i am not mistaken is a ground wire. On the PSI system there was a wire that went to this (again, if i am not mistaken, the PSI system would increase the idle a bit to compensate for the compressor turning on) and well after removing the PSI system and now have this wire to connect somewhere, typically i would just ground it out, but i was wondering if there is a wire on the Holley system for this. I know there is an AC shutoff and an IAC Kick, not sure if either of these are for that, and maybe i just ground the wire?
Hope this clears up my earlier mess, lol. Sorry about that.

Vintage Air can easily be integrated with the Holley EFI at different levels. I find that the IAC kick input is rarely necessary for a stable idle, but it can be helpful in some cases. The AC shutdown output requires a relay to be wired in conjunction with the Vintage Air wiring for the compressor relay.

Is the AC currently working properly without that wire hooked up? i have found that on 2 other cars i have with holley and AC that the IAC kick isnt needed for when the AC kicks on. if the motor doesnt bog down when the AC is on then why waste a input that could be used for something else. If the motor DOES bog down then yes i would hook up the IAC to the holley. i feel that this black wire your referring to is the IAC wire that tied into the old PSI harness.

I sent in an email to Vintage Air asking to clarify the Black wire on the AC unit, making sure i am not mistaken in that it is the ground wire.
Again, thank you to all of you for your responses. I know that sometimes these questions seem dumb or just crazy and so i appreciate you all taking the time to help out.

if im not mistaken the wire going to the compressor on the vintage air is a blue wire. you might be able to turn the key to the on position and turn the AC to on and see if the compressor clutch engages. if im not mistaken that is what mine will do on my vintage air. i have mine wired in with a trinary switch as well as a wire tapped into the signal wire from the vintage air so when it sees the 5v signal from the controller my fans kick on and stay on. just going off the trinary switch my fans would cycle on and off with the compressor clutch and while driving that was pretty often. (on for 6 seconds then off for 11). i have since found a leaking crimp fitting that needs to be replaced so that was probably my issue. i also have a I/O module so i have options to be able to wire in different things.
have you traced out the black wire to find out where its going? looking at the wiring diagram i dont see a black wire in the vintage air schematic.

Verdad Gallardo So to answer your question somewhat, when the engine was wired up with the PSI Engine Wiring and the stock style brain it was running and the AC was working. But since then i have removed the PSI wiring and installed the Terminator Max and now i am just finishing up the wiring for it and am down to the one wire from the AC and then i have the two others from the Terminator Max system, IAC Kick and AC Shutdown. This weekend is the planned first attempt to start with the new Terminator Max.
I sent in an email to Vintage Air asking to clarify the Black wire on the AC unit, making sure i am not mistaken in that it is the ground wire.

That means alot! Thank you sir! I have read alot on here (all positive) about you and your knowledge about the system, so I will take you up on the offer. I will try to not make the questions as open ended as this one was, and provide better info with it. Again, thank you sir for taking the time to share your knowledge and help.
