  • Fairing Electrics and Auxiliary Lighting

    Just installed an OEM set of passing lights and am also going to install my fairing as soon as I get it back from the paint shop. The fairing will have a radio and a switch for the passing lights.

    I plan on and assuming that I should be able to connect them to wires in the headlight bucket that only allow power to these 2 items when the ignition is on. Is there any particular color wires that I should connect to? Should both the radio and passing lights be on separate circuits?

    I noticed that there is an accessory light option (optional) #58 in the lighting system wiring diagram in the 2008-2010 service manual. Is this located in the headlight bucket and is this a good circuit to tap into?

      You can tap into the headlight bucket for a relay trigger wire but your main power will need to be ran on its own direct from the battery.

          I could do that for the radio but don't want to do that for the passing lights. Where can I get one of these relays you posted?

          I don't think that relay would work for what I ultimately want to do for the passing lights.

          The headlights do not come on until the engine is running which is what I would like the passing light to do also so I don't have to think about manually switching the passing lights on or off.

          So by looking at your relay diagram, the passing lights would come on as soon as I turn on the ignition on thereby stealing amps from the battery when starting.

          I noticed in the following wiring diagram from the service manual that the headlight relay has 4 wires connected to it. #47
          The Brown comes from the Signaling system fuse which comes from the ignition switch on a white wire.
          The Green with Blue tracer comes from the headlight fuse which is attached to the battery on a red wire
          The Yellow with Black tracer comes or goes to the ECU (this must be the wire that controls the headlights not coming on until after the engine starts)
          The Red with Yellow tracer goes to the headlight dimmer switch

          Couldn't I just buy another headlight relay and set it up with it's own fuse from the battery, tap into the Brown wire from the Signaling system fuse, tap into the Yellow/Black wire from the ECU, then run a wire to the passing lights so they won't come on until after the engine starts?

          Or can get an aftermarket relay that would do the same thing. If so where could I get one?

            Not trying to hi-jack this thread, does anyone know the part number of the headlight relay? (Number 47 in the wiring diagram)

            Thanks

              It's called a Relay Assy (5Ea-02), Part# 5EA-81950-20-00, Number 42 in the parts diagram.

                  Ok so in Morts diagram, 86 is the input signal wire to turn the relay on. If your profile were filled out with your bike info, it would be easy to direct you next, however the simple answer is tap into the power going to the headlight and attach it to #86 and the relay will turn on when the headlight does. If you have a newer bike (05 or newer IIRC) there will be a wire in the headlight bucket (think its blue with a yellow stripe, again IIRC) that is the power to the aux lights and you can use that one to turn the relay on instead.

                    Wow, my 2003 the lights come on when I turn the key on. You mean others don't come on until it actually starts? By the way, separate the power wires for the stereo and the lights. Most stereos have a constant power wire ( mine is yellow ) to retain the memory of the clock and the pre-set radio stations, and the switched wire ( mines red ) that allows the radio to be used only when the key is on. You could wire the two together but I've seen too many guys leave the radio on with the bike/car off and forget to turn it off and come back to a dead battery.

                      Yeah, don't know what year this changed with the lighting but I like the feature.
                      The relay has 2 hot wires going to it. One from the ignition switch through a fuse and the other from the battery through a fuse.
                      The yellow wire connects to the coil and the red goes live to the headlight when the coil is energized.
                      The coil does not does not get energized when the ignition switch goes on like your bike does so the headlight does not come on.
                      The negative wire on the other side of the coil is not connect to ground until the the engine fires up. Once the engine fires, the ECU connects the negative side of the relay coil to ground to complete the circuit which in turn flips the switch to the headlight. The negative wire on the coil ohms out as a broken wire until the engine fires up.

                      I set up the passing lights relay exactly like the headlight relay with 2 fuses and spliced into the negative wire from the ECU so that the passing lights come on after the engine starts.

                      If you don't use an OEM headlight relay to add this "on when engine runs) circuit to your passing lights. It's important that do not use a standard run of the mill relay. You need to use a relay that has a diode across the coil if you are going to connect the negative side of the coil to the ECU. The OEM relay has a diode. I don't understand all the specifics but from what I understand, I think you could damage the ECU without the diode relay.

                      Here's a link to a page that explains various relays including relays with diodes.

                        Sounds like a "fun" project but knowing me and electrical systems, I think I'll just let it be. Besides, someone already put a switch in line on the passing lights so I can turn them on or off whenever I want to.
