I don't know if the 04 is like my 06 k9 but on the k9 you will need to disconnect the tail light harness(white plug with wires running to each strut), then remove the 4 strut bolts and remove the fender. Remove the jst connectors from each LED board (this is the hard part) Remove each strut from fender (bolts are inside fender) pull the wiring from the tail light housing and reinstall. On the 06 k9 there is a grove in the struts were the wiring goes into. Not sure about the 04's. I think some had the wires running inside the rear fender. Hope this helps
I bought the struts from shovelhead kicker. Unfortunatly, the stock bolt which is hollowed out for the wiring is not long enough with the sissy bar strut. Also oddly enough its 5/16" on the outside and on the inside its slightly smaller bolt doesn't even fit all the way through the strut :bang:
I attempted to use the stock bolt and cut it down a bit and was able to thread it from the inside of the light housing, however I can't bite enough of the strut to make sure the tailight doesn't rattle loose :angry:
I read a previous post regarding someone finding some hollow threaded rod, I would be okay with making my own bolt and drilling out the strut to fit the 5/16" bolt. However, I'm up shit creek without a paddle I can't find hollow bolts 5/16-16 x 2" or hollow threaded rod anywhere! Found some smaller ones (seems like these bolts are specific to motorcycles and tail/headlights) but they just won't cut it!
Also, on 04's wiring runs through the inside of the fender, need to extend the wiring slightly.
These are on JP Cycles but 3/8 not 5/16 and i dont think 1.5" will fit. Need to bite the two piece light assembly on the 04! Don't know why they threaded it through the strut and 2 seperate pieces it makes it a pain in the ASS
