my wiring diagram doesn't show wires for the Idle actuator.
which wire should I use?

also on the manual it asks to ground microtech to battery but can I ground to Body. so I can share same ground with my LC1 so don't have to worry about Ground shifting? problem?

I thought this microtech install should be straight forward but lack of information on the manual really slowing me down.

 

I had the same problem i scrapped the idea and i adj. the idle manually.

 

I asked my local tuner and he said white/black aux wire and other side IGN +12.

 

Serious? I dunno I am new to these units but I haven't seen anything suggesting that one of the AUX wires controls the IAC stepper motor. Personally I am also planning on adjusting it manually with the idle adjustment screw.

 

Yes I'm very serious.
That's my microtech dealer said and he knows what he is doing..

 

From what i read in the manual and microtech's forum your guy is right you just need to set it up screen #29.
