Sur Ron Homoglation kit & other Tips & Tricks
Hey Everyone, I am iterating on other people's work (thank you).
I could never find a complete kit, so hope to have accomplished that below (sans headlight). Below is a full kit and ugly wiring diagram. I had no trouble registering it as a moped in CA and getting insurance via Geico.
What might be new about my kit is using the acerbis fender + brake light which attaches nicely to the sur ron fender - perfect size.
Note: When I took this pic of the plate, I had bent the fendor down using a heat gun. Don’t do that, tire will rub. License plate should be pointing up more to the sky.
As others have done, The on/off switch acts like the Sport/EP mode switch on the old controller:

I had to relocate the speedo using some random parts laying around:
Solid state relay (part # below) is attached using 3M Velcro-like stuff under the battery cover. I need to harden up the wiring a bit more somehow – too loosey goosey for my taste.
Parts:
Acerbis tail light/brake light w/ license plate light:

LED flasher:

Solid state relay: https://www.amazon.com/gp/product/B00B888WVC/ref=oh_aui_search_asin_title?ie=UTF8&psc=1 For brake light. It doesn’t look like the pic at amazon – looks like my pic.
Turn Signals:
https://www.amazon.com/gp/product/B00GU734UA/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 I bought this exact part from Amazon years ago for my KTM and the signals were super flexible, not anymore.
Would suggest getting ones that are more flexible for the rears which are the ones that tend to get destroyed.
Turn signal mounts:

Connector: https://www.amazon.com/gp/product/B0734P8F45/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 Just used one waterproof 5 pin connector from this kit to connect everything in the rear fender so I could remove the rear fender/seat easily. Kinda big, don’t love it but it worked.
Stuff I had laying around:
Shrink wrap
Extra wire
Wire jacket
Tools:
Heat gun, shrink wrap & an electrical tester comes in handy
Ugly wiring diagram. The hard parts are 1) the solid state relay, 2) to know to put the flasher relay going into the switch (obvious in retrospect). Maybe the next person to do this can make a nicer drawing:
Update: Diagram is out of date: I had some weird issues leaving the brake disconnect wiring in place in the harness like the diagram shows. I was always getting a ‘hot’ line coming out of the reed switches when hooked up to the sur ron harness, so I abandoned that and no longer use the reed switches to disconnect the engine on braking as originally intended – they are just used for the brake light.
Other Tips & Tricks:
- Reed switches: I fried mine (dumb mistake on my side). Neither Luna nor Sur Ron could provide a replacement part (which is a bit concerning that they don’t make all their parts available). I found that a reed switch m/n MK14-1C90E-500W works just fine, but I put two layers of shrink wrap over it because they were slightly slimmer in diameter.
- Giant Loop tail fender bag works nicely under the seat (I removed the plastic under the seat which didn’t seem to do anything and allowed me access to loop the straps around the sub frame). Not really easy to get stuff in/out of, but good for emergency tools/tube kit.
- iPhone 5 fits perfectly over the speedometer area, I hold in with a couple straps (only 1 shown) and giant loop fender hooks: https://www.giantloopmoto.com/product/fender-hooks-set-4/
- Topeak Mini Morph Bike Pump’s bracket nestles in between the battery and frame and with a couple straps holds in place: https://www.amazon.com/gp/product/B000FICCQC/ref=oh_aui_search_asin_title?ie=UTF8&psc=1
For new sur ron owners or people thinking about it:
- Bike is a blast in technical riding. You can do about about 25mi (3 hrs for me) of hard riding
- Check how the wires are coming out of the wiring harness out to the handlebars and how they are strapped (or not strapped in). Mine were strapped in a way that had a lot of flex and I was sure they would cause problems later.
- The pedal kit is bad. Its as if I made it in my garage – you really don’t want this on your bike unless you absolutely have to. It will cause problems.
- There is a connector under the seat that is completely open, find it, tape it off at least. Same for a connector in the wiring harness under the key switch. Just an open connector sitting there. To me, open connectors + water = shorts. Whoever designed the frame, motor and/or battery on this bike obviously didn’t oversee the entire wiring harness.
