Does your Big Dog have an issue?

Wire Plus has the "Perfect Fix" for all Big Dog Owners who are sick and tired of a bike that won’t start!

Wire Plus Powersports Electronics is proud to introduce their new, state-of-the-art "HCM" Retrofit Kit for all EHC module equipped Big Dog Motorcycles. This is the perfect fix for all Big Dog owners tired of not being able to start their bike due to electrical problems. This replacement module works with all of the switches used on all 2004 models through current Big Dog Motorcycles. Each kit comes complete with Wire Plus’ proven power module and switch control module configured to work with the ground input switches used on the Big Dog Motorcycles.

Wire-Plus products are built to survive the rugged urban environment. Their products feature vibration resistant, solid-state breaker technology (the breakers never have to be replaced) and a replaceable start relay that can be purchased at any auto parts store.

Their power modules are submersible waterproof and very compact in size with harnesses that are engineered to be smaller than any other on the market. The lighting control module controls the operation of the front, rear turn signals, and provides load equalization and auto cancelling.  It also operates the rear turn signals as brake lights and running lights with one wire hook-up. Wire Plus’ main focus is on the reliability of everything that they manufacture.

Wire Plus has added ring terminals, butt splices and wire to the kits to make the hook-up of the ground wires easier. They have also added wire and butt splices for the wires that have more than one wire going to a pin.
