tach wiring

[95sdime]

i looked in the how-to's and i might have missed it, but i got an aftermarket tach for my 95 s10 and i got instructions but they are pretty generic, is there any vehicle specific diagrams that i could look at?

Green goes to the tach signal (negative side of the coil, i.e., not the pink wire), white wire goes to dash lamps, red is 12V key on and black is ground. Should be all.

i know that this is a dumb question, but where is the ignition coil? i cant find it on my 2.2.... and when i do find it, how do i hook the wire up to it for my tach?

You will have to t tap into it, your tach should come with some stuff to tap into it. As for its location...i havent had much hood time under a 2.2....SPARKY

Well damn. Hmmmmm.......

Guess you're gonna have to find the tach signal wire in the instrument cluster. The 2.2 is DIS so no good tach signal there.

I'll see if I can't find a wire color and location.

It's the white wire in the Instrument Cluster connector. Looks like pin #1.

so are u sayin that i can just splice it into the wire that makes the light on my dash say shift up?? cuz if so that would be hella easier!!!

[95sdime]

hello? i need some help on the subject, can anyone answer ^^^^^ that?

[Sparky2263]

The shift lamp is turned on by the computer or cluster module. You need to use the white wire in the instrument cluster connector. You will find it when you remove the instrument cluster and inspect the connector.

i tried both of the white wires and one of the pink ones.. none of them worked! im supposed to use the wires that go to the connecterr into the cluster right?!? cuz thats what ive been using, thers 2 white wires and i tried both of them, and i tried one of the pink ones and im about to go try the other... HELP ME!!

Did you connect the green tach wire to the white dash wire, then hook up the positive and negative on the tach?

[95sdime]

theres only a positive, theres no negative on the tach, and i tried both of the white wires, and one of the pink ( i thought it would work according to the diagram but no) and nothin.. im all out of ideas so gimme any of urs! my truck is in pieces right now in the driveway

[95sdime]

i tried the negative too, nothing...

[T Man]

what do you mean there is no negative? Hook the positive up to a 12v source, ground the negative, then hook the tach signal wire up to the white wire in the dash connection, or pin 1 (i believe) of your diag port.
