Tachometers

For tach wiring, you would use one of the coil mounting bolts for the tach ground, use the red/black striped wire (either coil) for the power for lights on tach, and then the orange wire (right/battery side) or gray (left/kickstand side) for the measuring/feed wire.

From SilverBack: Barons Tach Install:

The "red / black" notation in the directions is misleading - it is NOT red or black but IS red-black STRIPED.

When the Barons Tach comes new - it has what 2 of what they call "piggyback" connectors - sort of like a Y but made of one piece of metal - female spade receptacle on one end and then 2 separate male spades on the other. Allows you to slip the female end onto the coil in place of the stock wire and then gives you a place to attach the stock wire and the tach wire. When I did my first install, I found one of the spades was too wide and I had to trim the edge (not easy, but doable).

When I moved that tach connection from the right to the left side (same time I installed upgraded coils) - and also when I installed a Barons Tach on a newer bike: I made 2 DIY Y's of my own.

For each one: female spade on the single end and then two male spades on the other - with the length of about 3 inches - used crimp-ons and then a dab of solder. Before I did the crimp and solder, I slipped on a piece of shrink tube in each end - big enough to cover the crimp-and-solder part of the male spades -- and big enough to cover the receptacle part and the crimp-and-solder part of the female ends. This provided electrical isolation of the final assemblies once they were slid into place and "shrunk"..

I also used dielectric grease on all connections - got small foil packet at auto parts store.

Wiring connections:

Before unplugging anything - make note of which wire is connected to which spade on the coil!! For "shits and grins", be sure to install to the right side coil (not the one with the rev limiter).

Tach Black (ground)- crimp and solder on a round terminal - will attach to one of the coil bolts.

Tach Green - crimp and solder on a female spade receptacle - don't forget the shrink tube!

Tach Red and Tach Blue - twist together and then crimp and solder on a female spade receptacle - don't forget the shrink tube!

For Y-1:

-- Connect the Red-and-Blue female spade receptacle to one of the male spades of the Y

-- Connect the Bike's Red-Black STRIPED wire to the other male spade of the Y

-- Connect the female spade receptacle to the spade on the coil to which the Bike's Red-Black STRIPED wire was attached.

For Y-2:

-- Connect the Green female spade receptacle to one of the male spades of the Y

-- Connect the Bike's Grey OR Orange (depending on the side of the bike) wire to the other male spade of the Y

-- Connect the female spade receptacle to the spade on the coil to which the Bike's Grey OR Orange (depending on the side of the bike) was attached.

If you forgot to or choose not to use shrink tube - wrap the exposed connectors in electrical tape - so they cannot touch each other!

Also two things everyone considering a tiny Tach should know...........

1. It has a 5 year battery and stays on all the time. When the battery dies you cannot change it.

2. Instructions say to use the white wire for ground but you don't have to do that and is a waste of time. It will work just fine by only wrapping the red wire around one of the spark plug wires a few times.

It should be at setting #1.
