Question:

If I add these extensions It looks like Ill need to add about 5-6inch wiring extension as well. Do you cell a wiringing extension kit for the Happy Jack motors?

Hey Greg, you shouldn't need any wiring extensions with the install of the Happijac extension brackets # HJ54FR. If you check out the attached picture you can see where a customer of ours installed these brackets and had more than enough wiring length.

Well that's great for him. I dont have that on my Northern Lite. When I swing out the dually extension that is factory installed it pulls the wiring taught. I dont have 5" of extra wire to account for adding the extensions I just purchased. Same on both sides.

@GregW I see what you mean. Sorry about that. We don't have an extension harness available so best option would be to cut the current harness and add in as much extension as you'll need.
