When purchasing my new 2007 Roadking, the dealer asked if I wanted a factory installed alarm for an additional $345.00, to add a siren was another $90.00 and add a pager $70.00 or a whopping total of about $500.00. I purchased the TW-400 for a total of $147.50, a savings of $325.00. This $325.00 will go toward Stage 1 mod's. The following is the step by step of my installation.

Step 1) Planning is one of the most important parts of a good job no matter what you are doing. I began by laying out the parts to determine, what else I would need before starting. Most everything was included, but I thought I would want more than the 4 tie wraps provided, so I purchased a few extra. Also, since there was several connectors, I purchased some Electrical Contact Grease, a necessity in the environment a motorcycle is in. I used HD 99861-90, but any good contact grease should do the job. I also noted that there were only two Posi-taps, these things were great so I purchased a few more, got them at Walmart.

Step 2) I followed the suggestion in the manual "Getting Familiar with the TW-400". I will not go through that, the manual explains it well. I confirmed that everything worked and now had an idea of what the different wires were for. Looked overwhelming at first, now it was almost simple.

Step 3) I removed the passenger and driver seat, the saddle bags and the side panels. This exposed all the areas I had available to mount the components. The Roadking has quite a bit of room and I saw several areas that would work, but I decided on the area between the plastic wire covers just in front of the battery. This area was as though it was made for mounting this alarm. I positioned all the components to make sure they would fit, and everything looked good.

Step 4) The speaker siren and perimeter sensor had mounting tabs that I would not be using (they have foam mounting tape on the back)so I cut them off with a pair of cutters to save on room.

Step 5) Before going any further, I disconnected the battery ground wire to be on the safe side.

Step 6) I positioned the speaker on the right side down in the space between the wiring channels. I removed the mounting tape, because it was not needed, and mounted the speaker facing through a hole in the metal, the fit was perfect.

Step 7) On the left hand side I did a similar thing with the siren, but I used the mounting tape to position it aimed through another hole in the metal

Step 8) I positioned the control unit down in the space between the speaker and siren with the antenna connection on the right hand side, coming up over the top of the control unit. and the wire harness connection the left hand side and secured it with the foam mounting tape, in a vertical position facing the battery. Again a perfect fit. I plugged the speaker and siren into there respective connectors after applying a small amount of electrical contact grease to the connections. Any excess wire was coiled up and tie wrapped.

Step 9) I fished the wiring harness up from the left side where I had removed the side cover (where the fuses are) and plugged it in to the connector on the Control unit. This positioned the TW-400 fuse with the rest of the fuses and if it was ever necessary I could get to the fuse just by removing the saddlebag and side cover. I mounted the antenna (see 14) in a space on the left side of the motorcycle along the rear fender, that would be under the drivers seat. Then I routed the cable back to the control unit coiled the excess and tie wrapped. I put a small amount of electrical contact grease on the connector and joined the two connectors and secured with tape and velcro so it would not vibrate loose.

Step 10) I removed the fuse going to the TW-400, so I could wire the red and black wires to the battery. I ran the red wire back up to the positive side of the battery, cut the wire to the correct length, stripped it and using the connector provided fastened it to the battery positive. I ran the black wire over to the negative side of the battery, cut it to length and crimped the supplied connector on the wire. I did not connect it yet because the ground is still off the battery. I connected the frame ground wire to the bolt that holds the battery in position.

Step 11) I mounted the perimeter sensor on the rear fender under where the passenger seat will go. This provided protection for the saddle bags. I cut the supplied velcro in half and only used half to mount the sensor. I plugged the cable from the control unit into the perimeter sensor again with a little electrical contact grease.

Step 12) I mounted the LED on the frame neck in front of the gas tank with a tie wrap around and existing cable bundle.

Step 13) The console was removed and the LED wire was run back to the control unit and plugged in.

Step 14)As mentioned earlier I mounted the antenna body on the right side along the fender so it would be covered by the seat, being careful to makes sure the whip part of the antenna did not touch any bare metal. You could stop here for a basic installation and skip to step 17.

15) Connecting the two yellow wires to the directional signals could not be easier. I just found the brown wire and violet wire for the directional signals in the harness on the left side of the motorcycle and using the two Posi-taps slid one base over the violet and one over the brown wire and then screwed the middle piece down on the base. The orange and white ACC wire was also right there so using a third Posi-tap that I purchased (the alarm only had two), I slid the third Posi-tap base over the orange and white wire and screwed the middle piece down on the base.

Step 17) Re-connect the battery negative cable with the TW-400 black wire and replace the fuse. Replace the seats and side panels and saddle bags. Note: before replacing the passenger seat, adjust the sensitivity of the perimeter sensor by watching the little red LED and adjusting the Potentiometer.

This completes the installation, time was about 1.5 hrs, much of which was the planning stage.

Note: I did not connect the ignition disable function. The pink and gray wire are connected to the contacts of a normally closed relay. The contacts open breaking the circuit when the alarm is alarming. These two wires can be connected in series to any circuit that when opened disables the motorcycle. If connecting these wires take a look at the side bar on the TW-400FAQ for some suggestions.
