Installation Instructions
RELAY INSTALLATION
1. Trim the red wire from the control as needed and
crimp on the supplied insulated terminal. Connect
the wire to relay terminal 87.
2. Connect the supplied green wire to
relay terminal 85. This wire should be
connected to vehicle ground.
3. Connect the supplied red jumper
wires to relay terminals 30 and 86.
4. The red wire connected to relay
terminal 30 should be connected
to an under-dash 12V source
(battery voltage) capable of
supplying 15 amps.
If needed, extend the wire to reach the
POSITIVE (+) terminal of the battery. The
extended wire will need to be protected by a
20-amp in-line fuse (not supplied).
5. The red wire connected to relay terminal 86
should be connected to a switched 12V source
(+12V when vehicle ignition is ON, 0V when
vehicle ignition is OFF.)
NOTE: When connecting to a fused vehicle
switched 12V source, always connect to the "load"
side (protected side) of the fuse (i.e., so there will
be no power if the fuse opens).
CAUTION
Connect green wire from ground to relay
terminal 85. Reversing this connection will
damage the internal relay diode, causing the
relay to be inoperable.
