This is what I've found out so far, there used to be a youtube video how to set it up but its removed :(

Here's what I have, pretty much stock engine

Between VTA and E2(ground) 0.65vdc@idle

Between VTA2 and E2(ground) 2.39vdc@idle

Other info

Between VTA and VTA2 1.75vdc@idle

Between VC and VTA2 1.75vdc@idle

Between VC and VTA 4.33vdc@idle

Mine has never been moved.

Wire identification-


Blue w/yellow stripe-VC

white w/red stripe-VTA

Green w/yellow stripe-VTA2

@68*F accross terminals VC and VTA2, you should have a resistance of 1.2K-3.2K ohms
