ECU and RPM help.
Hey guys,
This is a
flamer question but is the ecu under the dash?
Also i have a window switch for my nitrous but i dont know what output the RPM is on the ecu, does anyone know what prong it is or how i can connect the window switch in a different way?
Thanks.
Alex

alrighty thanks but can anyone help me with the second part of the problem?
what prong is the RPM input on our ecu, i look on the autozone thing that has the feltons and they dont have it in their diagram... so im stumped.

I leave the tach wire unhooked alot of the time on my own cars when I do remote starters.

or does anyone know of another way to get this to work?

i figured it out right after i asked the question... i was in one of those panic modes when i dont think and just ask questions.
Everytime the rotor hits the 1st plug it counts a revolution...
So would i splice RPM switch into plug 1?

Actually, this DOES help you - whether you have a 5sp(which I have) or auto-tragic (which I used to have). The wire is the same for both iterations. I simply made the comment to Brian because it's kinda hard to find (that wire).
But once you find it - and this is going on the premise that you have a DMM handy -meter it with your DMM set to AC voltage and the engine running. You should see the RPM's rise and fall with the press of the gas pedal.
I can give you a "pinout" (location of the wires on the ECU by number) if you REALLY need it. But going by what internetautomar gave you regarding wire color, and what I'm suggesting here should get you up and running without the pinout stuff.

BTW i dont have a DMM (is that a voltometer thing?) so im just going to have to guess and check.
Thanks for the help!

P.S. Nupe u going to GG?
