#4936, "SymTech IAC Wiring"


          

My MS2 unit was just delivered and I have a question concerning wiring of the IAC. It will be installed for full standalone.

Does anyone know the wire mapping between the MS2 wiring (green/white, white/green, blue/white and white/blue) and the connector wiring (yellow/blue, gray/blue, orange, and gray)?

Thanks in advance for your help!

Yes, I red that thread and many others. While that thread contains very helpful information, it does not answer my specific question.

I can tell you what worked for mine, but you will have to wait for me to take the tape off and check. I also installed standalone, and I JUST got it to work without any flaws.

I can tell you that for a standard MS stepper motor IAC rig, the green/white wire goes to JS3, the white/green wire to JS2, the blue/white to JS1, and the white/blue to JS0. Given Corbin's information, your connection scheme should look something like this:

white/blue = IAC yellow/blue stripe
blue/white = IAC gray
white/green = IAC gray/blue stripe
green/white = IAC orange

Is that a question? If so, you're not providing enough information; the SPR ports can be connected to anything and in any way. If you're sure they're connected to the stepper motor driver and I had to guess how, I'd say SPR4 is probably connected to JS3, while SPR3 is connected to JS2 and so forth. If that's true, your wiring scheme would look like this:

Grey = IAC yellow/blue stripe
White/blue = IAC gray
White/green = IAC gray/blue stripe
Blue/white = IAC orange
