Tach install on 2001 Suzuki Carry

    Can anyone tell me where to hook up the green wire on my tach to get the ignition signal? I tried the 3 wires on the cam sensor, no luck. Help please!

    Hey Mike same here on my 2003 none of the wires give a good reading. I have a Eqquos 6068 that you can configure for 1-12 cylinder engines and it reads on
    one of those Wires but not correctly it’s all over the place. Wish we could talk with someone at Suzuki to see where we could hook a Tach up??

    Yours is the only response I’ve received on this forum. I talked to a 4 wheel drive shop here that sells a lot of these trucks and they don’t know either.
    My problem is that when the fan is on in the winter, you can’t hear the motor. I thought a tach would help.
    If you find out anything, let me know.

    I’d be tempted to try the lead on the coil that goes to the points or ecm.

    Back before things got complicated, that was the standard place to wire the tach. But on newer vehicles you sometimes get multiple trigger signals.

    Thanks but no luck. I guess these new units aren’t meant for a tach.

    cam sensor? signal wire hooks up to coil negative, you just tap it into the coil negative wire. threw one into my Sambar last year. if it has coilpacks and no distributor im not too sure

    The coil pack is just a coil. And it has a feed wire and a trigger wire. But, you prably can’t hook to it because many of the engine control units send multiple trigger signal per cycle to the coil to promote cleaner combustion.

    If there was a stock version with a tach, they may have included a tach trigger wire on the ECU, and actually run a wire in the wiring loom to the tach. It is sometimes more economical for a manufacturer to include wires for every option, and have extra wires in some vehicles, than too warehouse and keep track of multiple versions, that they then have to warehouse, track, and get to the assembly line in the correct sequence for the vehicle they are building today.

    Try looking under the dash, and see if there is an extra wire, near the gauges. They might have integrated it into the harnas connection to the gauge cluster, so it may not be obvious. I’d rry pulling the connector off the cluster, and see if there are any positions in the connector which have a wire, but not a pin on the gauge cluster side to match it.

    I just received my Equus 6068 tach and noticed in the installation instructions the following:

    C. For conventional 4-cycle and Coil on Plug ignition systems, connect the
    GREEN wire to the negative side of the ignition coil (on Coil-On-Plug
    Systems, make the connection to the negative side of one of the coils only).

    Does this help you? What is the best way to find the negative side of the coil-on-plug?

    Hope this help there is a sticky on this page about the Tac set ups.
