There should be a light green or violet wire coming from speedometer this is your database wire. This is were you hook up your last wire. Hope this helps, from 04-to 07 the wires are pretty much the same color.

wires from speedometer:

light green/ violet = database
black= ground
orange/white= inst power+12vdc

    Also if you go to HD site and find the tach that you bought and view it it has a pdf file that tells you how to find the pins to connect to.

Tach signal wire

The tach wire will be a pink wire under the wire loom leading up to your speedo. It's usually tucked into the conduit. If you don't have it there, then you'll have to run one all the way to the ECM.

2005 harley fxdwg brake light works, tail light does not. replaced bulb, replaced tail light cover ?

The brake and running lights should run on separate wires from under the seat, through the hole in the rear fender and into a connector on the rear tail light cover. Your turn signal wires run the same path. These should all be clipped into place under the fender. I would look for a broken wire under the fender, especially at the point of the clip, or a corroded terminal in the tail light housing. The open wires are suseptable to rear wheel thrown road debris. You have easy access for a wire continuity test from the plug under the seat to the tail light cover.

Wiring diagram for mini tachometer kit

Most aftermarket tachs have 3 wires. 1 is the 12 VDC "power", 1 is a black ground wire, and 1 wire provides the "signal" to the unit from the secondary side of the ignition coil.

Tacho stopped

I believe the fuelpack uses the tach signal in its operation. For some reason yours is not passing this signal thru to the tachometer. I'd get in touch with the manufacturer. I'm not sure if there is some setting that can turn off/on the signal pass thru, or that your fuelpak is faulty.
