BMPRO TrailSafe, Owner'S Manual

Page: 14 / 24

Do not connect the Tr blue wire directly to trailer brakes if the SwayControl
is also installed. Failure to do so disables the unit’s ability to control sway.
WARNING
The return (negative) wires of the brakes and brake lights from trailer must be wired
directly to:
9
One of the negative output connections on BatteryPlus35 or J35 if fitted
9
To the non-battery side of a negative side shunt such as the BC300
9
Directly to the battery negative in all other cases
Ensure the house battery has a suitable charging source such as a BatteryPlus35,
J35 or other charging means and is functioning correctly. Refer to manufacturer’s
instructions for these products as required. A basic charging means such as diode
from the Auxiliary to the house battery may be employed in simple systems.
An external automotive-grade fuse is required to be fitted (30A maximum) between
the TrailSafe / Tr and the battery to protect against wiring faults and issues.
If you have a BP35/J35 installed, all negatives must pass through the BP35/J35
before connecting to the house battery.
WARNING
If you have a BC300 installed, all negatives must pass through the BP35/J35, and
then the BC300 before connecting to the house battery.
