Mounting Instructions GL1500
Simply place the unit on the right side over the battery, between the hold down bracket and the main fuse. It is designed as a snug fit and you may have to move the main fuse cover over a bit to wedge it in. I recommend placing some Velcro or quality two-sided tape on the back of the unit to insure that it does not come off unexpectedly.

Mounting Instructions GL1800

There are two ways to mount the unit on a GL1800.
1. If you do not have a CD changer, you can mount the unit in the compartment for the CD changer with Velcro or two-sided tape (not supplied). The wires are run from the trunk under the seat. After wiring, put the cover on the unit to prevent shorting.
2. If you do have a CD changer, you can mount the unit using a large peace of Velcro or quality two-sided tape (not supplied) in the left saddlebag on the left side, just above middle, in the flat area. Drill a hole large enough for the wires in the left top corner. Use care to only drill thru the saddlebag and not any other parts/wires. After running the wiring, seal the hole with RTV, Hot Glue, or other product to prevent water for entering saddlebag. After wiring, put the cover on the unit to prevent shorting.

Wiring Instructions All

NOTE: The black screw on the 5-position terminal determines the operation of the relays. If this terminal is connected to +12v then the relays will operate with a ground input. If this terminal is connected to ground, then the relays will operate with a +12v input.
Connect the main lead (heavy wire) to the battery positive post. It is recommended that you put a 20amp fuse as close to the battery as possible.
The lighter cable (black/red wire) can be connected to the auxiliary connections located on the left side of the bike just above the fuse box. Connect the red wire to the + terminal, black wire to the – terminal.

Unit Operation

When the bike is turned on, the wire to the ignition (usually the accessories terminals) goes to +12 volts and turns on the main relay along with its LED. The top two (right side) output terminals then have +12 volts directly from the battery. These connections are ideal for trailer lights, CBs, running lights etc. The remaining four outputs are designed to be switched and are controlled by the four left side terminals. A ground connection (-) to any of the four input terminals (usually from a switch) then turns on that relay and +12volts appears on it's corresponding output terminal, again directly from the battery, and lights that terminal's LED so you know at a glance that everything is working properly. Connecting any input terminal directly to ground will allow it's output to come on any time the bike is on.

Fuse Values

A 30amp fuse protects the battery line, a 15amp fuse protects the main relay, a 1amp fuse protects the ignition line, and each of the six outputs has its own 7amp fuse. It is recommended that you DO NOT change these fuse values.

Unit Overview

Unit wiring is neat, using much less wire. Smaller gage wiring can be used from the switches because of the relay's low current draw. This eliminates all the high current wiring to and from relays hidden all over the bike. Also eliminated, are these extra connections and the corrosion problems associated with the crimp type connectors commonly used on relays.

Since everything uses a common +12volts, directly from the battery, there is less chance of a ground loop. However, it is also a good idea to run all negative (-) connections directly to the battery and to NOT use the chasse as a ground.
