IMPORTANT NOTE:

It is unlikely your EHC died on it's own. In many, many cases a defective OEM charging system has caused the issue/s. It is a well know issue with the late 04 and up BDs. In addition your bike may have a/some shorts and wiring issues that need immediate addressing as well. Please do not just purchase the EHC, yank it out of the wrapper and throw it in hoping it will solve your issue/s. It may temporarily resolve the symptoms the bike is displaying but it will not repair the underlying issue/s that caused the symptoms in the first place. Also, often times with the EFI BDs the S&S VFI module may get damaged or it's software may get corrupted which will cause the bike to then not start even though the EHC has been replaced. WSW is here to assist you in getting your BD back on the road and reliable but it is not magic. It takes some due dilignece and a little work in most cases to get your ride back in shape and reliable.

Electronik's "Big Dog EFI Motorcycle EHC replacement" Version 2 is here.

This EHC is for EFI Big Dogs only. If you need the carb version please go HERE.

Don't hack up your Big Dog wiring or rip everything out just to keep riding it? Your Big Dog's electrical harness was manufactured with quality AeroSpace grade materials so don't let anyone tell you your Big Dog electrical system is trash or dangerous because it isn't. Like any system if you install it and maintain it correctly it will take care of you.

With revised circuitry and no more "Low Glow" of the Lo Fuel and Check Engine lights this is the "ONLY" true Plug N Play EHC for Big Dog Motorcycles on the market today. This Big Dog EHC replacement stands head and shoulders above any other competitor on the market today and all at an affordable price. Additional components have been added to insure the correct information is being sent to your EFI system. The new case allows you to simply drop it into your existing bolt holes, fender washers may be needed, included with this EHC, due to the oversized holes BD was using for their inadequate grommet system. This Big Dog EHC replacement stands head and shoulders above any other competitor on the market today and all at an affordable price.

Remove your old EHC, remove the D-Sub connecotrs, plug the two d-sub connectors into the new EHC and gently tighten the mounting screws, for later models you will remove the mounting grometts in the battery box that were used for the OEM EHC, clean the area with acetone or alcohol, remove the backing for the velcro tape, drop in the new EHC and press it down firmly to secure the velcro tape to the battery box. Thats it! Go out and ride. There are some additional items you will want to do though to make your ride reliable electrically.

Electronik has made many improvements to the EHC to prevent many of the issues the OEM BD EHCs had. In addition they have stripped out all the Service/Warranty bloat that lived in the OEM BD EHC. Less junk, fewer problems.

2 year manufacturer's warranty

This EHC is for EFI and Carb bikes.

This unit will work with the newer BD EHCs with the reverse D-Sub connectors. If your connectors fit into your existing EHC, as in the below image, then you are good to go. Otherwise you will have to send your old EHC to WSW so we can change out the D-Sub shells for you. There is no extra charge for this service.

Note: If you have a Big Dog factory air ride system then you will have to put in an alternate switch to control the air ride. WSW offers a kit utilizing Electronik's "Air Ride Switching Module" for your air ride equipped BD that makes maintaining your ride functionality a breeze. This module plugs into your existing harness and comes with a new harness and mini switch that you can mount just about anywhere. One push of the button activets the compressor. Two quick successive pushes of the button activates the air relief solenoid.

"OH NO! I already hacked up my OEM harness" Not an issue. Email us at wsworx@gmail.com and tell us which year and model you have. If you have a Chopper and the VIN number is "5J11T" instead of "5J11N" then you have a Daytek frame and we need to know this when you email us. We can get almost all of the harnesses.
