Bro, I don't even know where that is. I'll have to look it up.

LOL... on the ST205, it attaches to the battery tray and looks like this: Image

Not sure on the ST185, but it should look very similar and have a 2-wire connector that goes to it.

And the relay is to the left of the radiator. In a mini fuse box

The relay has the FP mod. I never disconnected the resistor, would that even matter?

So you have the pump running full time? If it's not running then I would assume that yes, something isn't right with your pump wiring

Alright!! Figured out that the circuit opening relay was crapped some how, replaced it and he's back in the game again!
