Subject: Help!!! How Can I Find My Tach Wire
Date Posted: February 02, 2003 at 2:39 PM

I installed a Bulldog RS-85 remote starter in my 96 Corolla. Anyway it wont completely turn the car over so the manual said to go Tach mode, but in order to do that I've got to find the tach wire. All I know is it should be going into the ECM but where's that too???? And how should i locate the wire once i find the ECM

Any Help Would Be Greatly Appreciated

Thanks

Kev

You can use an injector wire,  there are two wires to each injector and there is one wire that is the same on all of them, use the unique wire on any one of the injectors.

Or you can look for a black wire at the check connector, which am not positive where it is on your car, but I all the toyotas I have installed on I have seen it near the passenger side fender wall toward the front oif the car.  I usually use the injector wire since it is guaranteed.

Sorry to bother you again, but when you said the unique wire did you mean the one that was different on each injector or the one that was the same on each one. Just want to double check before I start fooling with this stuff.

Thanks Again

grab a wire that is different on each.  I thought that might have been confusing, good for double checking though.

you have to use the wire that is different color, in almost all fuel injectors you wiil find a wire that is the same color, use the other color. or run a wire to the tach wire at thw check connector. Make sure you learn the tach to your remote starter.

TACHOMETER|black               |   |check connector or at the coil same color
