This is the Bike we are installing the TW-400 Security System on, a 94 Softail Custom. This bike did not have a lot of spare space, we spent a little extra time placing the components in different positions, until we were satisfied with the lay out we were going to use. We decided to mount the Control unit under the seat along with the Motion Detector. The Siren and the Speaker we placed between the gas tanks, the LED is on the frame in front of the gas tank, and the Antenna, we mounted on the inside of the sissy bar bracket.

This is another closer view of the area under the seat where we are mounting the Control unit, this particular bike has sheet metal from a 95 Softtail, so we took advantage of the plastic compartment in the rear fender, and with some minor modification we installed the Control Unit in the plastic Box. Before finalizing the location we replaced the seat to be sure that things would all go together as planned.

Next, we removed the instrument housing and leather pouch, exposing the area between the two halves of the gas tank. This would allow us to get to the ignition switch and mount the siren and horn between the two halves of the gas tank. We mounted the siren and Speaker, one to each side of the gas tank half, ran the wires back to the control unit and plugged them into the appropriate color coded connectors on the Control unit.

We taped the wiring harness next to the control unit, because we did not want to apply power to the alarm yet. Since we were going to have to run the brown wire up to the key switch ACC, we decided to run the red wire that goes to +12VDC up there too, this would eliminate another wire on the Battery Positive terminal. We checked the wiring diagram for the ACC and then verified that the terminal we choose received 12VDC when turned to ACC. We connected the brown wire to this terminal. The red wire we connected to the terminal that was always +12VDC on the key switch.

We then connected the Black wire coming directly out of the control unit to frame ground, This can be any good electrical connection to the frame, we choose a bolt located near the control unit. We then connected the Black wire in the wiring harness to the battery (-) Negative terminal. So far so good, we only had 4 wires left on the wiring harness, two yellow and a gray and pink wire. Next we decided to connect the two yellow wires to the directional lamps, one for each directional. Looking at the wiring diagram we discovered that the wires would be brown and purple. To test that we had the correct wires we stuck a safety pin into each wire and with a short wire touched it to +12VDC to assure the directional lights would light.

The wires were located in a a wire bundle on the left side of the motorcycle next to the battery compartment. We then carefully removed about a 1/4"" of the insulation on each the brown and purple wire and soldered one yellow wire to to the brown and one yellow wire to the purple and taped it with electrical tape. We could have used wireless connectors but we felt this was a cleaner installation. If you are not comfortable with soldering, or the thought of stripping wires on you precious possession, you may elect to have professional do these four wires, although there is really nothing to it.

We almost forgot about the LED. We ran the LED between the Gas tank and mounted it with a small piece of double sided tape, on the frame just in front of the gas tank. We then put a small piece of black electrical tape over the base to blend in with the frame. We could have drilled a hole and mounted the LED in the console, but we found this to be more than satisfactory, with much less work. Well, only a couple of things left and we are all done.

The Pink and Gray wire are next, the Installation manual explains this pretty clear. We found the wire that goes between the Ignition module and the coil, cut it and connected one side to the pink wire and the other side to the Gray wire. Again, if you do not have confidence, you can have this done by your local bike shop. Next we plugged in the antenna and mounted it with Velcro, next to the alarm, with the antenna following the curvature of the rear fender. Finally, we mounted the Motion detector on top of the electronic ignition. That is all that is to it for the wiring.

Finally, we plugged the wiring harness into the Control unit, and were ready to test it out. We turned the key switch from off to ACC 8 times, on the 8th time the LED lit, this was our sign to push one of the buttons on the LCD transceiver. The siren sounded once, we turned the key switch to off and the installation was complete. All that was left was to replace the console, pouch and seat.
