I remember there was some discussion about this sometime back but I can't find the post. Can someone describe to me how I can jumper my fans so they turn on at the same time according to the thermostat? I have a 00 miata.

Thanks!!!

Thanks Chuck.

Do you have a diagram of what the pin outs look like? Also, this is to jumper the signal (i.e. not the power lines) correct? From my recollection, jumping the signals is much better than jumping the power lines.

That's what I was looking for!

You just have to connect those two together.

The way Tom and I have it wired is by using a short length of wire on the PC Pro wire harness (not on the ECU harness) and using a male/female connector to connect the two. This way, you can always just disconnect it quite easily.
