One of the trickiest thing about wiring a lot of electrical accessories onto a bike is dealing with all the wires and fuses. We'll install a GPS, radar, set of lights, and one or two other things on a given bike and end up with a real rat's nest of wires coming off the battery, with a cluster of in-line fuse holders (some glass, some blade) that have to be kept accessible to allow blown fuses to be replaced without tearing the whole bike down. The obvious solution is an auxiliary fuse block. We've tried a bunch of them, and usually they're so bulky that they are hard to hide, or they don't have a grounding block so they only take care of half the problem.

The Centech AP-1 is by far the most useful auxiliary fuse block we've found anywhere. Its small size - 3.0" x 2.4" x 1.24" - allows it to fit almost anywhere. There are 5 fused circuits, and 3 of those have dual terminals - great for allowing a couple of small items (GPS + Radar for example) to share a single circuit. The AP-1 can handle up to 60 amps total load, and can be wired directly to the battery or through a relay for switched operation (relay not included).

Connecting to the AP-1 is simple - there is no need to crimp terminals onto your wires, just strip a short piece of insulation off the wire, insert the bare wire into the opening on the terminal strip, and tighten with a small screwdriver. It's that simple! There are 8 power ports for the 5 circuits (3 of the circuits have 2 ports apiece), and 8 grounding ports on the opposite side of the panel. Included standoffs allow the Centech to be fastened to many locations. We often find that it can be bolted directly to the rear fender under the seat on many bikes, or sometimes we fasten the Centech to a piece of scrap plastic or ABS and Velcro it in place.
