MPS Sport Bike Electronic Engine Kill Installation Instructions
The first thing to do is remove the seat, fuel tank, and
possibly the front fairing if equipped. You will need
plenty of room to work.
Electrical Connections – You will need to locate and
test a few things on your bike before you start wiring. A
good ground, a ignition switched 12 volt power source,
the horns, and the ignition coils. We have plug n play
style harnesses available for some bikes. Check the
web site for specific models.
Control Box Wiring Coils –Most four cylinder
motorcycles use either a individual firing system or a
waste spark system. Waste spark is by far the most
common. All four cylinder bikes with only two coils use a waste spark system. Most late
model four cylinder sport bikes use waste spark systems even though they have four
individual coils. Some of the newest fuel injected bikes (Hayabusa, GSXR1000, ZX12) that
have cam sync sensors are individual firing.

This is a typical 4 coil wire diagram. Generally the positive
wires are all one color and the negatives for each cylinder are
all different colors. The brown wires will tap into the
negatives of each coil.

The Sport Bike Engine Kill has four brown wire leads that are connected to the negative of
each individual coil on a four coil system. On a two coil system you will use only two brown
wires. Some two coil systems will not have enough kill time. If you experience a kill time that
is to short you can ground the remaining two brown wires. This will increase the kill time.
You can either solder the brown wires to the coil leads (recommended) or use the provided
scotchlok splices. Race bikes with Dyna Pro 4000 Ignitions can use one brown wire
connected to the orange kill wire with the other three brown leads grounded. MSD Ignitions
