Help rewiring AC to Haltech

[Draimond]

The A/C switch I would take a signal off that at 12vdc, then you need to buy one of those solid state modules to drop it down to 5vdc for the ECU, maybe haltech has them? then connect the DPO to the clutch relay.
I think that should work, I might be wrong, waiting on Lout or one of the other auto electricians.

I'm a mechanic not and auto elec.

Yeah, think we're pretty well on the same page.
But the Haltech has it's own dedicated +5V supply / output for us to use with any sensors / AVI's etc. Pretty sure I've got a spare relay or two floating around.

Gave Haltech a call this morning and it looks like the AVI's aren't exclusively 5V.
Just have to set the voltage I want it to turn on above and the voltage it turns off below.
So 10V + on, 2V or less for off.

So that basically means there is no wiring needed.
Take the 2 existing wires that run to the factory PCM and re pin them for the Haltech. The rest is software. Mint.
