Was reminded this evening that this had never been posted after it came up in discussion in another thread a couple of weeks ago.  If anyone is interested in retrofitting the power saddlebag locks from the 2007 bikes in to previous models it's not a terribly difficult thing to do.  Remainder of this thread will illustrate the install and detail the do-s and don't-s.

First thing to mention is the parts to do the job are surprisingly few in notated HD part numbers.  Also surprisingly inexpensive (relative to common HD standards on such things).  Ordered from Zanotti (far and away the cheapest) the entire parts list was approximately $275.00.  Only costs above that were a few bucks worth of wire.

That wire, however, is the only part that might push some people off this task.  At least right now Harley will sell all the mechanical parts, motors, etc.  They don't have a separate part number for the wire harness to tie it all together though.

Even though it is effectively a stand-alone harness I assume it must be supplied on the SEUCs wrapped within the main harness's insulator.  No part number for the saddlebag lock harness.  So you've got to build your own.  Fortunately it's a simple little harness.  Even more fortunately you can find a schematic for it. 

That schematic is the image attached to this post.  Notes are added to the schematic in four places.  One is a hand drawn diagram of the relays.  You'll use two of these.  They are identical parts.  They are wired differently.  But the relays themselves are identical.

Note the two legs marked as ground wires.  In the larger schematic page they end up in different locations.  Don't let that worry you.  Ground is ground.  You're making your own harness anyway.  So bring them out of the harness wrap close to a good ground point and bolt them down at the same place.  No big deal.  I grounded mine at the bolt on the right side of the frame close to the cruise control switch in the throttle cable.

Another leg is marked as the power wire.  You don't want this hot all the time.  You only want it hot when you've turned the switch on.  If you walk away from the bike with switch unlocked now anyone will be able to turn the switch on and push the button to unlock your saddlebags.  Just something to keep in mind.

I powered it from the back of the lighter.  That location is already fused in a place that doesn't require pulling the fairing.  There is no draw from the new locks during running operation of the bike.  So it's an easy and obvious place to power the system.

Last note is of a diode that must be installed between the legs that run back to the saddlebags.  The motors in the saddlebags operating these locks don't have separate ground, lock and unlock wires.  Just two legs run to them.  With the relays used as they are those two legs alternate between grounding and lock or unlock functions.  Because of that wiring scheme you need this diode installed between those legs.
