I traced my faulty fans on my 2dr Sierra back to the plug on the harness that goes to the switch. I have hunted high and low and not able to find the right plug for the factory sensor. Any ideas?

May have to grab an aftermarket sensor and plug and wire it in but would rather stick with the factory switch...or perhaps make a loom and use an Escort two stage switch. I am in Australia and being warmer like the idea of one fan kicking in around 82deg. I have seen thermostats that open earlier so will be grabbing on of them as well
