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

well im sure u can cuz i found a post that muythaibxr has worked on a 7 that had them working through ms, so my question is what circuit would i have to build, like a diagram and/or description and parts list would be awesome

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).

here is this the diagram of the circuit i have to build? if so if u have the time can u please explain the diagram to me i dont really understand it, cuz i know that the transistor has three leads but how do i know which one goes to which, or does it not matter?? also the diode in the diagram is pretty much like the one for the efan and bac on aaroncakes website, correct?
thanks for ur time

heres the diagram

 

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

can i use js7 js9 or js11 for the output rpm signal?

 

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.
