The PWM cable I'm referring to is the one for the pressure sensor, not the relay/spike.

The pins I am connecting it too are the PWR and (-) pins, which are the middle, and outermost/closest to the edge pins. if you have the 3 pins like this " " " we are hooking the wires here " 0 0 the 0s representing our connections. This is viewed as the parallel port being at the top, and the RSL at the bottom.

I read in another post the it should be hooked up like 0 " 0 but I have no idea.
ohhh
um you need to have the power and signal pins hooked up to the sensor, otherwise whats reading the signal? the ground? certainly you wouldnt want that

and normally when something gets really hot thats a sign that you shouldn't be doing it. my guess is you are either arcing it or giving it an area of high resistance due to the small contact area.

you might also want to put a ohmmeter to the sensor to see if its still working after the various "tests" you put it through. ime its pretty durable, but you never know.
