76229-00 (antenna cable) - this is the extension cable that came with my quick release tour pac kit (53246-09) on my 09 EGlide.

 

i have a 09 roadie and when i put on the king tour pack theparts guys got me all i needed to make it a quick and easy job to install and remove.the only problem is that reception is not as good when tp is on.be carful when you buy hidden ant. most don't work worth a beans

 

i put a tour pac on my 08 road glide a month ago, the extra cable you are looking for is under the left side cover and is plastic tied in place to the right of fuse block cut the plastic tie and pull the cable from under the seat you will have more then enough cable the light wires and antenna cable are in the same plastic wire cover

 

Ucomm, there is extra wire there for the antenna? Enough to reach out to the tour pak?

 

yes, the antenna wire is in the plastic casing that also holds the wire for tour pac lights,cut the plastic ties along top of frame holding antenna wire in place and work your way foward, it will go into a plastic casing that both antenna cable and tour pac wires run through,the wire goes down into the left side cover and is in a loop on right side held in place by a plastic tie,cut the plastic tie holding it in place and gently pull up through hole, there is at least 10" of wire run along frame, secure in place and into tour pac
