I used the IC Dynamics Remote Keyless Entry System model 2RTA. This consists of a small module with a 10 pin connector. I removed the unused wires leaving only the 5 wires needed.
Wires needed from the module are...
White
Red
Black
Green
Yellow
The unused wires may be removed completely by using a sharp point and pushing in on the pin release on the side of the connector.
Both the Red and White wires have an inline fuse and both need to be connected to the positive terminal of the battery. Since there was no need to have two fuses, I connected White wire to the Red Wire so that they shared a single 15 amp fuse.
Now you should have just 4 wires coming from the module. (Red, Black, Green, Yellow).
Next it is time to work with the lock relays. They are located together at the end of a harness on the right side of the fairing. To give myself some working room, I carefully split the black wrap around the wire bundle back about 4 inches. This makes it much easier to access the wires as they go into the bottom of the relay sockets.
First find the two large Red/Violet wires. These wires supply switched battery power to the lock relays. Cut these two wires, then cover the open ends (with some heat shrink) of both as they come out of the wire bundle. You won't need these. For the two Red/Violet wires coming from the relay socket, you should connect them together and then to the positive side of the battery along with the Red wire from the module. This will give both the module and relays power 100% of the time. This is the most difficult part because you will need to run an unswitched battery line up.
Next, locate the Green/Black and Blue/Black wires. These are the Unlock and Lock control lines respectively. If you want to keep the dash switch operational, then you will be splicing into these lines. If you do not want to keep the dash switch, then cut these wires and terminate the wire coming from the bundle and only connect to the wire from the relay socket.
Connect the Green/Black wire from the relay socket to Green wire from the remote module.
Connect the Blue/Black wire from the relay socket to the Yellow wire from the remote module.
Last, connect the Black wire from the remote module to the bike chassis (Ground).
And that's it. I used some wiretires to hold the black cover back in place over the wire bundle going to the relay socket.
Let me know if anything wasn't clear. - Keith
