SP1 Fan non-op

I had my RC in traffic for the first time the other day, and sure enough a few lights in a row and saw temps heading to 240 before I got moving and cooled it down.

I have started to dig into it (BTW this is a recent purchase which I got fairly inexpensively, knowing there would be a bunch of niggly crap to deal with), anyway this is what I found.

1) 2P connector is a drift and therefore not grounding??
2)Wire to thermo switch is in the breeze also...

I had already jumped in and have a bracket from Wibbly on the way, thanks mate! And a Spal on the way off of Amazon

I guess I am looking for confirmation that the connector grounds via the tab which should be attached to the rad...

the ground is supplied by the thermal switch on the radiator.


power goes into the fan, then off to the thermal switch.

Copy that, also see a black wire connected to the back of the rad from the 2P connector. (the one the zip tie is pointing to)

I have some cleaning up to do in there with the weirdo indicators that are hooked up.

Rear harness is freak'n mess too, so many dodgy connectors.

What gauge wire should I be using when I am cleaning things up?

And should I go with a regular connector that I can shrink wrap?

don't use connectors if you don't have to. solder and shrink is the best method.

This may help you with the wiring diagram, and if you want to wire in a toggle switch, that's an option too.
