Installed HD adjustable backrest on 08 flhr today. I don't like how I had to rout the cable. It passes from the adjuster lever which mounts to the frame under the left side of the seat rearward to get back to the mount assembly up on the fender. To get through to the back the only passage I could get through is the same one that the drive belt goes through. It is a big passage and the cable is at least two inches above the belt but it doesn't seem good.

Anybody else with this problem? I would like to know how to rout it anywhere else. I tried for hours and this is all I could do. The instructions are sort of vague. Says to go between the electrical box and the battery but I could not get through even with loosening the box. This wasn't supposed to be hard but for me it was.

Thanks

The adjustable backrest was not designed for the changes that HD made in enlarging the fuel tank in 08

That being said.. It wasn't easy, but I was able to route thru the frame plate under the seat. There is a hole on each side, but they do not line up. I was able to get it thru and not pinch it. I recently removed the cable due to adding heat shields, so I am sorry I don't have a picture.

I simply keep the rest locked where I like it, and don't need to change it anymore.

 

Poorly designed and that's it. I spent a few hours one day trying to install that thing on my 08, last year (before I bought my Mustang) Finally got it in and took it for a spin with my wife and we both came to the conclusion it sucked! Big and bulky and gave her no room in back. Bought the Mustang seat with adj/removable backrest and never looked back.

Yes, I had to loosen the fuse panel to get it in, and yes it had to go into the previously mentioned hole in the panel behind the motor. I wouldn't recommend routing it where you did above the belt.

 

I am thinking about leaving it like it is for a while until I can get to re-routing it. Can't not ride and nobody here freaked out and said I should halt. Hoping its okay to take care of it in a week or so.
