Bought to replace the EHC on a 2003 Big Dog Bulldog. Got instructions from Thunderheart for moving 4 wires. EASY install. Used a ford tractor ignition switch to replace the BDM switch.

Bought to replace the EHC in a 2003 Big Dog Bulldog. Works perfect. I called Thunderheart to get the sheet to move a few pins around. Just followed the sheet and it works perfect. You need a new ignition switch. I bought a ford tractor ignition switch from tractor supply. Minor filing for fit.

Works great! Easy to understand instructions, even for an electrical idiot (like myself).

Quite possibly one of the single best products one can get from J&P. This has everything you need for wiring a bike whether you're building one, customizing, or replacing a poorly designed OEM wire set.

it made wiring the bike very simple. all the wires are labeled so you know where they go. it is a great part to use if your building a bike.

Used this to wire my first custom built bike. Made wiring simple. Don't know how it could be made any easier. Well worth the money spent.
