CRF1000L 3 Circuit Solution Leads

Basic Components:

In the picture below are the components laid out under the seat. They can be tied down wherever is convenient.


On this Africa Twin, a Japan market bike, an ETC automatic toll collection device comes at the front of the underseat tray. There is plenty of room above it as shown here. This location is where you could put a PC-8 fusebox as well if you require more accessory circuits.

In the pic below from the other side, you can better see the ETC box.

Here you see the circuit output connectors before circuit wires are plugged into them.


The main leads are easily fed to the battery. There is a channel for them as shown here upper right of the battery box. By installing this pair of heavy duty wires with high temp tough sheathing on them, you won’t have to access the battery again. You can power all your devices from a PC-8 or a 3CS. You’ll only have the one set of extra battery terminals so when it comes time to remove the battery it will be very easy. You won’t have messy wires all over the place and possible shorts around the battery.


3CS Leads:

Various pre-built leads are available for running your circuit wires from the 3CS under the seat to up front to power a socket, SAE, aux lights, or other devices.


On the left is a sealed both ends unit suitable for 2 wire connection. On the right an unsealed connector is installed as a terminator if required.

Various lengths of 3CS Leads and connectors are now available here to make your install super easy and high quality.

Various adapters and splitter will be available to put into your devices on the ends of the 3CS Leads.

Lead Installation:

From the 3CS the leads are fed along the gas tank as shown below. The tank left side covering is removed.



Further up the wires will go well above the hot radiator, bundled to existing wires. Cable tie the leads up to the level of the green line under the letters in the pic below. These leads were not yet tied up in this pic, so that they would show up better.



Bring the wires up behind the air intake hose and push them straight right bringing them into the power socket area. Use cable ties included with your Kit to secure all wiring safely to avoid chaffing or stress.



Here are the sockets I have installed on a splitter on one 3CS circuit. The automotive socket can power my air pump or two USB sockets with an insert. The panel mount Coax socket powers my GPS. It is installed in a factory hole that comes with a grommet in it. If there is interest I could source and sell these sockets.


You won’t have to take off many parts but the left outer fairing cover has to come off. The socket inner housing is detached and pulled up to gain access to the power socket mounting area. You don’t need to remove the wind screen or touch the right side unless you want to mount a socket over there. The turn signal assembly unbolts giving you access to the socket panel area mounting. Mount your sockets or whatever, plug in the 3CS Leads and reinstall everything and you’re done.


Various splitters will be offered, here is what I used, a Powerlet type socket connector and an SAE plug. I will consider making and selling splitters that you, my customers want.



NOTES: Using a sealed type connection is always preferable, but unsealed types are easier for the home user to work with. In many cases too, an unsealed type comes on some devices. The SAE type is not really sealed. The unsealed types shown above left fits most Powerlet type sockets and can be fitted with a rubber boot if desired. Sealed types are difficult to split, so wires are joined in their middles. It’s a bit more work and cost a bit more. I would suggest completely taping over a connector like the one above on the right. Until recently all bikes used unsealed type connectors for all connections. Even now, likely half the electrical connectors on a bike are unsealed types.
