Forgive me because my electrical terminology is lacking... but here we go.

I have a 3 wire PWM IAC. My strategy was to use a 33ohm 75w resistor to jump the closed wire to ground and actuate it with the FIdle_out to the open wire.

My stock ECU sends 1-12v waveform to either open or closed pin on the 3 wire PWM
But the megasquirt diagrams show FIdle_out as grounding the sensor.

Is there an easy way around this?

Here was my idea:
1) jump the 'open' wire on my IAC to 12v with the big resistor
2) hook FIdle_out to the 'close' wire on my IAC
3) hook the third wire on the IAC (was grounded) to 12v

The idea being it reverses the direction of each "open" and "close" wires, so I reverse the function of each.

Does that make sense?

OK scratch all that I figured it out.

This may sound really stupid but I can't find in the manual for the life of me how to wire up the fast idle wire through the DB37. I know there is a really simple diagram in the manual but I've been scouring it for the last hour and can't seem to find it for the life of me.

If anyone has any idea please post up. Even if it's like "hey look in ______ section"


Thanks,

OK I figured that out too (lol).


Now I don't have spark. That's another story.
