First, I have no coolant temperature coming to my cluster. The cluster has been refurbished and is known to be fully functional. I have the M20 temp sensor in a Texhnica water pipe adapter, and I'm thinking that it's not adequately grounded since the water pipe has o-rings on either end. I plan on adding a ground wire to test the theory, but maybe someone can confirm or deny this?
Next, I'm using an aluminum e36 radiator with my swap. It has a port on the passenger side for the fan switch, but the plug it shipped with has a rubber o-ring and the E30 fan switch has a crush washer. Should I be ok to swap them out, or do I need a different fan switch? I want to use the E46 fan module and I have the hardware to do it, but was hoping to delay the wiring adventure until after the car is running reliably. I tried turning the fans on with the AC button, which used to work, but now only the stock Aux fan comes on and my SPAL puller doesn't respond. Any thoughts on this are much appreciated.
