outputs

im just wondering if there is anymore output pins i can use to run my vdi, i already have a pump from a crown vic's lumber support, im just tired of turning on the pump with a switch manually, im already using iac 1-a,b and 2-a,b for the coils and e fan, but i dont know if there is any other outputs, i ran a search but came up empty, if not then i can probably run an rpm switch or something.
thanks

Tofuball collected most of the parts... He had a pressure switch that would turn on the pump when it dropped below 5 psi. Then we just wired that up, and let the MS control the solenoids (aux and vdi). We just wired two of the spare outputs to relay-trigger circuits (can be found in the ms2/extra and ms1/extra manuals).

Yes it matters which transistor lead goes where... If you don't understand the circuit diagrams I'd recommend buying a board that has everything already pre-labeled. You could get one of Jean's board or my board (Zeal Engineering) from DIY autotune.

ok i looked up some info on google and have one last question on the side that connects to the the spare port u see that there is a diode there my question is that diode inside the ms box or is it like an e fan and bac valve and is outside by the relay and if it is inside what i can i connect it to to get a 12v power supply, other then that i understand what i got to do,
thanks

If you're using the stock ignition system, the RPM output comes from the trailing ignitor.

I put the diodes inside the MS and that worked fine for me.
