Awesome, Randy - I get it now. Phew... not nearly as easy as I thought it would be. I'll have to ponder if my little project is worth the cost of the MCAW PLUS the cost of a replacement switch bar.

QUESTION: I assume the "auxillery" connection on the MCAW is in ADDITION to it's functinality as an auto-up device? So, I'd get that MOD (which I've been toying with doing) PLUS the ability to drive an aftermarket device with that switch? Sounds like you just wire in whatever wires would lead from the relay to the switch into there, correct? Also, you said it has TWO ports... does this mean that somehow two different devices could be wired into the MCAW and controlled by that single switch somehow? I don't think so, but the comment made me wonder...

Thanks!!

 

Thanks for the quick reply. This is precisely the information I needed . I am going the OEM route. Simplistic and elegant. Less chance of me screwing things up.

After ordering both the toggle and fog light, my next project is the autoup circuit . Is the MCAW the best one to get? Will it affect all the other functions? Thanks.

 

Yes you would still get Auto-up and the ability to add the auxiliary output functions. There is also the ability to auto disable DSC/ASC and yet another output to hard wire a garage door opener to the MCAW and trigger the garage door opener from the lock/unlock switch. All from the MCAW Deluxe circuit.

Yes it can control two different auxiliary devices. A brief click of the rear fog light switch will trigger one device and a long click of the (same) rear fog light switch will trigger the second device.

The connector is a small pin header connector on the MCAW circuit - similar to what you see sometime on the inside of a desktop computer to route audio from a CDrom to the motherboard. The cable simply pushes onto pins on the MCAW circuit and you wire the other end of the cable directly into your relay wiring. The MCAW doesn't come with this cable but they can be easily purchased online from several vendors including this one.

The MCAW Deluxe Installation programming guide has some pictures of where the cable connects on the circuit for the aux outputs. The PDF can be downloaded here - Page 10 shows the connections for Auxiliary Outputs 2 and 3 - the two outputs that are triggered by the Rear Fog light switch.

I think the MCAW is the best but I'm biased since I am involved with its support . The stock functions work fine with either the MCAW or Ians Auto-up.

They both work perfect. I don't think (but I'm not sure if) Ian's Auto up has auxiliary output functions for third party devices via the rear fog light switch like we have been discussing here but I am sure once Ian returns from MTTS with his new GP that he may comment on that.
