I damaged it a little during my header install and want to know if this is pluged on enough for it to work. The little metal prong was a bit loose but not to bad. I have the connector pushed on as far as it will go but it doesn't want to go on any further.

That looks like your fan switch. If the secondary fan comes on then it is plugged in far enough.

So explain to me the difference between primary and secondary fan switch's. I only have one fan. If the primary one fails does it go to the secondary one?

Single fan, eh?

I doubled-checked my Helm's. On a quick look through, it doesn't say anything about a single fan car in the troubleshooting area except it still shows it as the fan switch.

I suppose it would be just another thing that can turn on your fan. In a dual fan car the ECM turns on the primary fan. Turning on the AC does too. The secondary fan is turned on by fan switch when it reaches its temp or the AC reaching a certain pressure.

Maybe someone who has a single fan car will chime in.

Us single fan guys are just about the same. Our one fan is controlled by the switch in the head or the AC. The ECM has nothing to do with the fan in a single fan setup. Somebody correct if im wrong, but i am pretty sure of this.
