2016 32SA power window switch problem

Having an issue with the wiring for a 2016 32SA drivers side power window. I was replacing the switch which was functional but cumbersome with the a new switch from Tiffin. When removing old switch a lot of the wires came disconnected before I could ID the location. Four of the six wires are labeled which seem to identify to the motor - up and down. The other two were not labeled but you would think it would be easy as one is red and the other yellow. I would think that would be the ignition power and the lamps. My problem is I blow a fuse every time I hook up all the wires. When I hook up the motor wires I don't blow a fuse but nothing work either. When I hook up either of the unlabeled wires to the ign power I blow the fuse. When I unplug all and replace the fuse and test the wires. the motor wires have current running thru them with the ignition on. The unmarked wires do not. Should there be current in the two positive motor cables when not connected to the switch? I purchased the new switch from Tiffin which changed from a 6 pole to a 9 pole. I bought their harness to do the conversion and followed their wiring diagram to make the connections. I get the same issue

I have a 2015 32SA, the switch has a defect in it. It's actually very easy to fix your old switch and there is a good chance it will work fine.

Here is a link to a Facebook post that describes it with pictures.

You need to join the open readers Facebook group which you may find useful in general.

I'm pretty sure yellow is ground. Run a multi-meter to a ground and see what the ohms are.

I replaced a switch a little while ago, but didn't keep pics of the wiring.
