4 Circuit Solution Sealed Kit for CRF1000 (for modest power users)

Complete plug and play with all the wiring, a 20A relay, and a 3 circuit fusebox.

Read more about the 4CS-S here. See pics of it installed here. Note, all 4CS Sealed have been updated with new Furukawa modular fuseholders as shown below.


- 3 switched circuits are only hot when bike is on

- 1 unswitched circuit that is always hot, can be used for battery charging

- 35A total capacity - 20A on the 3 switched circuits, and 15A on the unswitched circuit

This Kit uses all sealed connectors, (shown above even the relay is weather proofed). The relay switching and ground wires plug into the existing 6P connector at the far rear of the under-seat area. Three mating sealed connectors are included to install on your circuit wires, to plug into the Kit’s outputs.

This Kit is available in two versions:

Battery Connect version - connects directly to your bike’s battery

Powerlink Connect version - connects to a large HD connector which connects to the battery - buy battery leads separately below

Crimper for sealed connector terminals:

The Hozan P-706 does a professional job on these types, go here to buy. This is a great tool for a home shop, most connectors on modern bikes are this type.

You don’t need a crimper to install these. You can pinch and solder if you know how to solder. I have a page about crimping and soldering here.
