Well made good progress today. I watched an YouTube and identified the colors of the wires to the unused OEM amber front turn signal lights.

This guy also said the white plug I asked about was hot all the time. SO, I used that to power the horn. I removed the positive wire from the plug and soldered my horn power lead to it. So getting the horn working was pretty easy. I mounted the horn under the front rack. I will post a picture of that location later.

What he did was much more complex and involved. I would note that I was trained in electronics in 1965 in the USCG, was a Field Engineer at NCR in the 70's and retired as a network design engineer at BofA/EDS. This kind of things is more or less in my wheel house.

Now knowing the left and right turn indicators use the light blue and orange wires, and from a cable by the master cylinder with a blank plug in it. Testing show that these wirers went to the front turn indicators and the left/right turn arrows in the instrument cluster. So I have the front turn indicators and the arrows wired to my handle bar switch. I have not cut any factory wires so far

I picked up a mini Add-A-Circuit to pull the turn signals power from the fuse panel.

Relays to do the 4 way flashers will be here tomorrow. I will have to use two(parallel them) as I had ordered SPDT relays.

Cost so far, with not much more to buy.

$7.63   License plate lights
$7.63   Relays for 4 way flashers
$10.90   LED rear lights
$27.26   Horn, handle bar sw, and blinker relay
$8.34   Add-A-Circuit
$5.00   Miscellaneous supplies
$66.76   Total

Does anyone know what the un-used white connector by the steering column is for. Appears a first glance to be a black wire and a red with white stripe.

I have to find the wires to the un-used front amber lights if anyway has info on that.

Ok, working on wiring diagram. The Red latching button is going to be 4 way flashers. I spent a lot of hours trying to design it with the existing brake lights to also be the rear turn signals and gave up as having them as turn signals and 4 way flashers was to complex. So I am going to installed two pop in Red LEDs on each side.

Start working on street legal project. Dealer wanted $700 plus to do it. So Amazon was my friend. I installed mirrors and a turn indicator switch which came with the horn and blinker. It has a red button for lights with I am going to use to kill/enable power to the winch in out switch. I did that on my Kawasaki KRX 1000 in Arizona, to help preventing two block the winch in an accidental hit of the in button.

The mirrors I bought on Amazon would not screwing into the threaded hole on the hand brake reservoir, so I used the included handlebar clamps on both sides. I had to reword the winch in/out button, putting in on the top of the handlebar. Opened up the mount and turn the switch over. I also had to bend the L mount a little to line out to the mount on the handlebar. Less than a L now.

I had to remove the left hand grip and switch assemble to slide the turn indicator/horn switch on. The mirror mounts are two piece and not and issue.

More to follow as this project moves forward. Planning on taping into the 2022 amber lights in the headlights and using red pop in LEDs on the rear (two on each side) on the rear. With wire and plastic loom I am still under $100.

Bought a new 2022 grey 600 touring today. Going to pick it up tomorrow.

I am looking at buying a CFORCE 600 Touring for summers in Washington. I have a Kawasaki KRX 1000 for winters in Arizona and bring my Can Am 2018 Spyder RT Limited Chrome back and forth. At almost 78 is this the right ATV for a active old man widower? I want the two up machine  incase I find someone that wants to ride along. I have a young widow lady in Arizona that rides in the KRX with me in the winter.
