Make connections as follows:
YELLOW wire of adapter to NEGATIVE on front coil (use the spade connector and the piggyback on your

BLUE wire of adapter to NEGATIVE on rear coil (use the spade connector and the piggyback on your stock
coil)
GREEN wire of adapter to green wire of tach (input) (Use the butt connector)
The GREEN wires ONLY connect to one another; DO NOT CONNECT them to any positive power source or
you will burn the unit out.
RED and BLUE or YELLOW wires of Tach to POSITIVE terminal of coil (or other switched 12-volt source)
BLACK wire of tach to CHASSIS (ground)
To determine POSITIVE and NEGATIVE of your coils: Most motorcycles will have two wires going to each of
the two coils. Each coil will share one common color wire and will have one different color wire. The common
color is positive, and the different colors are negative. For example: Yamaha has a red/black wire on both coils
- that is positive. The other wire is orange or gray - that is the negative side. Honda is black/white for positive,
and blue/yellow and yellow/blue for negative. Suzuki has orange/white on both coils as positive, and white or
black/yellow as negative. Kawasaki has red/green for common positive, and black or black/green for the
negative side. Harley Davidson has yellow/green for common positive and the negatives are blue/orange for the
front cylinder, and yellow/blue for the rear cylinder.
