So I've recently installed a MegaSquirt PNP2 in my '89 Fox and so far I love it. I love learning and tuning it myself. Already feels much better than it did with the A9L with a tuned SCT. I run dual Contour cooling fans which draw a lot of amperage on startup so I wired them into the MS separately. I wired them into output 1 and output 2 which are pins 24 and 25 on the options port. This supplies a ground signal when enabled.
My question is what can I use to turn my water pump on and off? I don't like my water pump running with key on engine off as it draws about 10amps so it's a battery killer if not planning on starting the engine. Also don't like the extra amp draw during cranking. I'd like to have my water pump come on after startup if possible. Has anyone done this? What wire can I use on the options port? Is it a ground or positive signal?
Under the Boost/Advanced tab and programmable on/off outputs I have FIDLE, Tach Out, Injector C, Injector D, Boost. Can I use one of those?
Thanks in advance for any help or guidance.
