Replacement for the Big Dog EHC module on 2004 through 2010 BDM. Works with the switches used on 2004 through current Big Dog Motorcycles. Includes our proven power module and switch control module, with built in auto-cancelling, configured to work with the ground input switches used on the Big Dog Motorcycles. This replacement module is the fix to get rid of the EHC for good.
You must also replace the ignition switch, when installing this kit.  We recommend the WP148.
PLEASE NOTE: Expected delivery time 1 - 2 weeks. Please call for most up to date lead times.
If you choose overnight shipping please note that your order will be shipped overnight after the parts are built.

Rating 2004 Big Dog Chopper
This is a well thought out system, easy to install! The supplied directions and diagrams are well laid out. If I pick up another Big Dog for our shop to resale I will automatically trash the stock EHC and put in this unit.

Rating Great system
Thanks, Wire Plus. I installed my new module in my 04 Big Dog Chopper, with no problems. It was actually fun. With so many wires to convert, you would think that at least one of them would be a problem, but everything worked first try. I have had absolutely NO problems since replacing my stock EHC, and it cured my low beam problem as well. I highly recommend this product to anyone who has a stock system.

Installed this kit for a friend and I must admit it was challenging but very well thought out. Only problems I had was installation of the new key switch took some modification and I came up short on butt splice connectors. Fortunately, I had some so it was not a big deal. The correct crimper tool is a must and wiring experience is needed. Gina at WP was very helpful with questions I had. This system works great and solved the EHC problem. If you take your time to read and understand the instructions, everything will turn out great.
