Welcome to the forum Mark. I will try and answer your questions.
Re the paint - I had 2 different paint shops match the cobalt blue & black paint. One shop did the mirrors and some work on engine parts, another did some work on a custom king tourpak. In both cases I never gave them a paint code but they may have gotten one from the dealer. In both cases I gave them a factory painted piece (side panel) to ensure a match. It shouldn't be any problem for a decent painter to do a match for you but I will ask the painters I used if they have any further info that would help you.
Re the Intercom - I posted a review of the product (Baher) in a seperate thread on this forum titled "You can have intercom"
http://flhrsei.org/cgi-bin/yabb/YaBB.cgi?board=eg_gen;action=display;num=1086143344;start=I am still very happy with the performance of the intercom unit and am considering changing out an Autocom system that I have installed on another bike for the Baher.
Re Heated Grips - The grips are completely internally wired. I believe you will find several threads that discuss in detail how to internally wire the HD grips, both on this forum, the Electra Glide Garage -
http://forums.delphiforums.com/electraglide1/start, and the V-Twinforum -
http://65.38.172.84/forums/index.php?. I wont bother to repeat what these threads already talk about except for one thing. I routed the wiring from the left side grip that would go to the power source through the grip housing where you see a rubber plug, and into the bars via the switch housing. I notched the inside ring of the switch housing to accomodate the extra wiring and left enough slack both under the fairing where the wires exit the bars and from grip to grip to allow for removal of the grip if need be.
Hope this helps. Let me know if you need anything else & I will try to answer any other questions you have.
