BMW R1200RT / K1200GT - P3 Installation
The water-cooled R1200RT for model years 2014-16 uses an LED tail light and require slightly different wiring than previous models. Click here for 2013 and earlier.
Remove the seat and locate the fuse block in the right front corner under the seat.
2016 Model: connect the controller's red wire to the red/green wire at this fuse block.
2014-15 Models: connect the controller's red wire to the red/brown wire at this fuse block. See photos below.
Note: power remains on to this connection point for 45-60 seconds after the ignition is turned off, so the P3 Lights will remain on during this period. The current consumption of our P3 Lights is very small so this delay will not cause any appreciable drain on the battery.
You can even convert the stock top case light on the BMW R1200RT model to a combined tail light/flashing brake light. Detailed instructions are available here.
2016 Model: under-seat fuse block wiring,
2014-15 Models: under-seat fuse block wiring,
Next, as shown in the photo on the right, locate the thick wire bundle in the left rear corner under the seat that goes through the tail section to the back of the bike.
Remove a 2 inch section of the black tape wrap to expose the wires.
- Connect the controller's white wire to the grey wire with black stripe (brake light wire). - Connect the controller's black wire to the brown wire (ground).
If you are installing the P3-TS model with turn signal capability:
- Connect the controller's yellow wire to the blue wire with black stripe (right turn signal)
- Connect the controller's green wire to the blue wire with red stripe (left turn signal).
Programming on the R1200RT-W (2014 and newer models)
Note: The brake light on BMW's water cooled R1200RT stays on for a minimum ~ 1/2 second after you release the brake lever or pedal, even if you tap the brake lever for a shorter period. This requires you to enter the programming pulses more slowly than on other bikes. When you release the brake lever or pedal, you need to watch the brake light to see when it goes out before you can enter another pulse.
The current IQ-260 series controllers (version, v10) have a programming method that accounts for this delay. but you still need to wait for the brake light to go off before entering another pulse.
On our earlier P3 Lights controller's, up to and including firmware version v9 (marked on control module's label), this brake light peculiarity restricts the number of brake light pulses that can be entered within the 5 second programming window. Please consult this section for programming details.
2005 - 2013 Models
From 2005 through 2013, the BMW R1200RT & K12/K1300GT use two, single filament brake light bulbs, rather than normal dual-filament tail light bulbs. There is no tail light filament, and consequently no tail light wire to provide power to the P3 Lights controller. Power is taken instead from a wire in the diagnostic plug as described below.
The following instructions illustrate how this is done on an R1200RT. The K1200GT is very similar.
Remove the front and rear seats and place the controller in the space behind the rear seat.
Then remove the two black Phillips head screws behind the turn signals so you can pull the tail light housing off.
Remove the tail light assembly, and install two gray/red Posi-Tap® connectors, one to the brown wire and one to the gray/black wire. Either brown ground wire may be used, and either gray/black wire on the center two lights may be used.
Run the controller's black and white wires from under the seat through the tail light opening and connect the black wire to the tapped brown wire, and the white wire to the tapped gray/black wire.
Next, locate a switched 12 volt source where you will connect controller's red wire.
The first option for switched power on this bike is from the diagnostic plug. The diagnostic plug on the R1200RT is located under the seat, circled in the photo. It is a round 10 pin connector covered with a cap.
The color of the wire to tap does vary by model year. On the 2009 it is a green/yellow wire as in the photo. On the 2013 use the green/blue wire in pin #10. Place a Posi-Tap® on that wire and connect the controller's red wire to the tapped blue/green wire.
A second option is the alarm connector under the passenger seat. If you do not have an alarm system fitted to your bike, this connector is taped to the frame, otherwise it is plugged into the alarm module.
Place a Posi-Tap® on the green/white wire and connect the controller's red wire to the tapped green/white wire. This provides a source of switched power for the P3 Lights system.
Install the LED modules on either side of the license plate with the lower license plate bolts, as shown in the top photo the R1200RT / K1200GT section, using the included license plate mounting hardware.
The wires from the LED modules may be run up the sides as shown below or through the hole just under the center of the license plate, then up under the fender.
Connect the copper wires to the ground and the silver wires to the controller's gray/green wire as described in the standard installation instructions
Secure the controller under the seat using the included velcro squares.
Bend the aluminum LED module brackets so that the LEDs are pointing straight back to provide maximum visibility
Convert Topcase Brake Light Into a Combined Tail Light / Flashing Brake Light
-Applicable to both K1600GT/GTL and R1200RT
If your K1600GT/GTL or R1200RT has the built in topcase brake light, it is possible to re-wire this light so that it can be driven from the IQ-260 controller from the P3 rear system and function the same way as the P3 Lights LED modules. In this configuration the stock topcase light will come on as a tail light with the P3's unique visibility flicker and when the brakes are applied it will flash brightly. It will also flash when the P3 system's emergency flasher mode is activated. If you do not have the BMW light option you can install our LED modules there instead.
Note: the P3 Lights controller powering the stock topcase light must be the non-turn signal version. If you already have the P3-TS model on your bike, you can add an IQ-260 control module to perform this function.
Topcase Wiring Instructions
If you have already installed your P3 system (the IQ-260 controller and LED modules) then skip to the section below where the photo lists 3 steps..
New topcase installation with or without our LED modules
Locate the cylindrical topcase connector, at the rear under the seat.
The connections should be made on the left (bike) side of the connector, so that you can remove the topcase without disturbing the wiring.
Follow the 5 steps in the photo on the right.
In step 2 connect the Posi-Tap® onto the bike side of the cut wire and then insulate the cut end.
In step 3 you will also connect the silver wires from the LED modules to the gray/green wire if you are installing a P3 system as well.
In step 5 you will also connect the copper wires from the LED modules to the Posi-Tap® on the brown wire if you are installing a P3 system as well.
(Note: power remains on for ~ 30 seconds after the ignition is switched off on this wire. P3 Lights draw very little current so this is not a problem.) To have the lights turn off with the ignition, you can connect the controller's red wire to the bike's yellow low beam wire or any switched output on a supplementary fuse block.
Add topcase to existing P3 system
When you already have a non-turn signal version of our P3 rear system installed it is easy to connect the stock topcase light into the system.
Follow the 3 steps in the photo on the right.
In step 2 insulate the cut end of the wire that is on the bike side.
In step 3 strip 3/8" of the insulation from the end of the cut wire that runs to the topcase. Connect it to the controller's gray/green wire, along with the silver wires from the LED modules.
Install P3 LED modules in TopCase
If your K1600GT/GTL topcase does not have the brake light option, you're in luck. You can install our P3 system and it's LED modules directly into your topcase, in the same space where the BMW light would normally go. Then instead of having just a medium brightness brake light, you get two very bright tail lights with our patented conspicuity flicker and extremely bright, flashing brake lights. In this installation you can use either a regular (P3) or a turn signal version (P3-TS) of the system since there will be two lights in the topcase. Not only is this setup much more visible than the BMW light, it is also much less expensive.
The P3 LED modules mount directly on the filler panel that comes with the topcase as shown in the photo on the right..
A description and photos of how one customer installed this system may be found on the K1600 forum here .
Wiring diagrams for this configuration with and without the turn signal feature are included below.
