Alternatively, you can locate the solid gray wire in the main wiring harness that leads into
the Borg Warner control box under the dash. Use a blue “Tee Tap” connector to connect
to this gray wire. You can then attach the gray rpm sensor wire to this using a push on
spade connector. The black wire can be securely connected to any suitable ground.
LS -1 On this engine (pre 2002 only), you only connect the Black wire on the RPM
Sensor cable to the Gray wire leading to the Borg Warner control box. (same as LT-R
MasterCraft). The gray RPM sensor wire is left un-connected.
2005 Malibu – See plug & play harness.
(4) 1999 – 2001 MasterCraft, 2000 Supra, 2000-2002 Infinity (All Other Brands Using
Borg Warner Gauges)
TBI & Multi Port Engines (except LT-R) – Locate the solid gray wire in the main wiring
harness that leads from the engine into the Borg Warner control box under the dash. This
solid gray wire carries the raw engine rpm. Use a blue “Tee Tap” connector to connect to
this gray wire. You can then attach the gray wire on the rpm sensor to this using a push
on spade connector. The black wire can be securely connected to any suitable ground.
LT-R / LT-1 - On this engine the Gray wire lead on the PerfectPass RPM Sensor cable
is not used and can be taped off. The separate Black wire end must be connected to the
Gray wire located in the main wiring harness leading into the Borg Warner MDC Control
box. It is on the engine side of the box that the raw rpm is located. You can attach a blue
“Tee Tap” connector to this Gray wire, and attach the RPM sensor cable end to this “Tee
Tap” using a supplied spade connector.
(5) 2000 – 2002 Nautiques
Same as standard #1 above, except the rpm signal can be picked from the Gray wire
coming from the back of the tachometer.
(6) 2003 - 2005 Nautiques
Located behind the dash pod is a large wiring harness with a large white plug. The Gray
wire in this plug carries the raw rpm of the engine and has been brought to the pod solely
for the PerfectPass system. This gray wire is not connected to any gauge. Use a blue
“Tee Tap” connector or other splice method to attach the gray wire on the PerfectPass
rpm sensor cable to this Gray wire in the harness. The Black wire (ground) on the RPM
Sensor cable can be attached to the black wire in this same boat harness.
Step 6. Install Paddle Wheel speed sensor and connect to Master Module. (See attached detailed
instructions). Note: On most late model boats, a paddlewheel is already standard so PerfectPass
did not supply a second paddlewheel.
Step 7. Test system power by turning on key. Following a short delay the black servo knob should be
difficult to turn indicating system is powered.
A final and easy test to ensure servo motor and cabling is wo rking properly is to turn key OFF,
then turn the black knob on servo motor counter clockwise by ¾ of a turn. Now turn key ON
and system should perform an “Auto-Tighten” function and wind cable in a clockwise direction
until tight.
(If motor does not wind in, but simply vibrates for 5-6 seconds, the servo power cable at Master
Module may be plugged in upside down or a connector at servo motor may be damaged. (Pull
plugs apart and inspect pins).
