If it is like mine (06 comfort ) and you got all cables it should only take a couple of hours to install the kit.
You will have to pull the left pocket and all the plugs are there for the intercom and power for the cell set.
You didn't say what model you have, but I just installed mine today on my '04. Just took a few minutes once I figured out what the separate components were.
I didn't think the instructions were all that clear, but I'm not the brightest bulb around either.
If you have a 12 volt accessory plug installed, you must unplug that and plug the power supply cord in there, then plug the accessory plug back into that. If you don't have one, the power plug is just under the air vent in that boot. I think it is red.
Then you have to separate the intercom wire plug that is just under and to the right of the pocket hole. I think it is red also. Plug in the intercom adapter and then replug the connector you unpluged back into that.
All the rest of the remaining connectors will plug into each other and they will only fit the correct ones.
The hardest part for me was running the connector for the GPS under the plastic baffle along side the rubber hose and up the handle bar. Be careful to leave just enough slack to give enough reach for bar turning but not too much to catch on something. It will fit under the plastic cover under the left handle bar and be hidden well.
