Where To Tap Rpm Signal?

[Khadgar]

Ok i bought a wideband command now i need to tap for an RPM signal, ti says to tap the switch wire on the ignition??/

Well anyways, what is the best place to tap to get this?

thanks

Pics? =(

I'm a tard.

Btw anyone here installed a maft before?

I see you have that gay ass 1995 shit going.On the firewall side of the timing cover, there are 2 harnesses coming out of the timing cover, an upper and a lower.The upper one should be the cam signal.I'll have to look around to find the wire color.

I suppose you could hook it to the tachometer wire also, but depending on the input impedance of your wideband commander, it may not work.And I suppose if you can adjust the RPM input on the commander, you could just hook it to one of the coil trigger wires on the power transistor, but since we have waste spark setups, that will only be half the RPM signal, so unless you can set the commander for 2 cylinders it won't work..

I'll do it to the cam signal I guess, I know eactly what connector you are talking about, my electrical service manual shoudl tell me which wire it is right?

Would it work to grab the uncommon wire on the injector harnesses? We use that a lot for tach reference on remote starts. I used the cam angle sensor just because I wasn't sure, but on a 95, if it works, the injector harness would be easier.

Khadgar, what I mean by "uncommon" wire is that there are two wires in the harnesses that plug into the injectors. One is the same on all of them, and one will be a different color on all of them. The "uncommon" one is the tach reference. Like I said I am sure it works for remote starters and such, but am unsure for any other application.

Good luck.

I'll just grab the CAS, I dont want to fuck with my injector harness more than i have :fworld:

I hate cars.

[Khadgar]

I give up guys, I just fucking H-A-T-E this car. Just.. UGH

GOD DAMN IT WEHRE ARE YM DOWNPIPE NUTS...
