Sure would be nice if this works...
I have a DIYPNP that I need to control an aftermarket two-speed/single fan with in a 93 Mustang. I have the fans controlled by two separate relays that are energized when ground is applied. When either single relay is energized by itself, the fan is on low, when the other relay is energized at the same time, the fan is on high.
What I did was jump the ALED to the EGR Solenoid, and the WLED to the diverter valve, pins 32 and 33, inside of the DIYPNP. Then tomorrow I'll wire these unused circuits over to the fan.
My other option was to utilize the 18 pin connector opposite the 60 pin on the megasquirt, but its kind of a pain working on the top side of the ecu while in the car.
I was a little confused by the 94-95 fan control scheme, but it seems to me that with it's separate fan control module, none of that applies to this vehicle. While I was in there, I wired up the input for the second o2 sensor. Don't have the (semi) sequential module installed yet so it wont really do much except verify the operation of the first o2.
