If you're looking to switch over to all LED turn signals, Doing this mod will correct the feedback issue that causes your turn signal indicator to stop working, and remedy All 4
turn signals coming on together. You will still need to wire in
resistors(waste of power/time/$ IMO) or replace the stock thermal flasher with a electronic flasher unit($9 on ebay/Plug and Play
), to correct "No Flash" and blink rate...
Hey guys, I searched the forums for info on this mod before I took the project on for myself. What I found is vague information, generic pictographs and a lot of you still asking questions. The clearest instruction I found, recommended cutting up the factory harness to splice into the turn leads(green and grey) and adding a ground to the frame. While this will work, the diode kits are fragile, use 22 gauge wire(very thin with rigid wire diodes attached), requires you to add an unsightly and exposed ground, and splicing into a harness near its connection point, is never a good idea.
My recommendation: Keep the install clean and weather tight, and inside the instrument cluster...
Remove the single screw holding the speedometer bezel in place.
Lift the tail end of the bezel upwards to clear the trim ring of the speedo and rock it left and right while holding the front of the bezel and pulling it forward until it slides off of the two steel guides.
Pull down the rubber boot at the front underside of the speedo cluster and disconnect the harness by pushing in the button facing the front of the bike and gently wiggle side to side while pulling down.
Lift the tail end of the speedo above the standoff and rock forward, left and right as you did with the bezel.
Ok, you have done half of the physical work(reassembly comes later). Now take the speedo cluster into the comfort of your home or workshop, to a well lit work area. Grab a coffee, beer or whatever and get comfortable...
Put newspapers or a towel down, and set the cluster face down on top of it. Carefully press the rubber bushing through the hole at the bottom of the case, it is holding the two half's together and will prevent separation if left in place. Next, using a Phillips screwdriver, remove the 5 outside perimeter screws.
Once the screws are out, carefully flip the speedo over and separate the speedo face from the case body. Locate the 8 wire harness below the speedometer, leading from the small indicator board, to the header on the speedo circuit board.
Using your fingers or a small flat blade screwdriver, gently pry the header free and then remove the single Phillips head screw holding the indicator board in place.
Remove the indicator board from the casing, and set the casing safely aside.
With the indicator board removed, our job just got easier!
We now have all the room we could ask for to install the diode kit, in the comfort of your work space, away from the bike!
*An EASY winter project.*
Here is a picture that shows what all the wires are for, but the only ones we will be concerned with are numbers 2(GROUND),5(RT SIG +),and 6(LT SIG+)
Carefully count over from left to right, to wires 5 and 6, cut them(in half) halfway between the indicator board and the header for the speedo board.
Strip no more than 1/8 inch of insulation away from both sides
of wires 5 and 6
Next, use a razor blade and remove a 1/8 inch of insulation from around wire number 2 nearer the indicator board side. Without cutting through the wire!!!
Using a good soldering kit, and your favorite solder(I like 60/40 @ 240C degrees ) attach the two positive leads of the diode kit(mine was CustomDynamics Red) to the header(speedo) side of wires 5 and 6. It does not matter what wire you solder to which lead, just solder one to each of them. Don't forget to put the heat shrink on the wires before you solder them!!
The single lead on the tail end of the diode kit(mine was White) gets soldered to wire number 6 on the indicator board side. Again, Don't forget the heat shrink!!
Your last connection! Wire number 5 of the indicator board needs to be wrapped around the exposed copper of wire number 2 and solder them together. There is no need for heat shrink or insulation on this connection as it is a ground inside a closed case, but some of you may prefer to do so just for good measure.
All board connections completed.
Re-install the indicator board into the speedo casing and replace the single Phillips screw that secures it. Reconnect the header to the speedo board and fan the wires to the right so that they neatly rest under the speedometer face. There is plenty of room to tuck the diode kit wires under the indicator board and keep them out of the way.
Here, I would have shown a completed picture, but I reached the maximum number of pics allowed. Besides, if you followed along, you already know what it looks like!
The final step is to put the speedo back together by replacing the 5 screws on the back, replacing the rubber bushing in the bottom hole of the case, and putting everything back on the bike.
It does not matter if you use LED's or standard bulbs for your turn signals after this mod is completed. The indicator lamp will continue to function as it was always intended. Doing this mod will
allow you to swap out the clusters standard indicator bulb for LED if you choose to do so, as the polarity no longer reverses when Left or Right turn signals are activated.
Enjoy your new mod!
