Hi all,
I recently purchased the Euro LED turn signal kit to eliminate the US pods and attempted to install with ScooterWest YouTube video but cannot get the blinkers to work.
I may have connected wires incorrectly cannot seem to find any videos or photos showing the correct placement of wires.
If anyone can assist me I would highly appreciate it.

I'm not able to personally help with this, but if you can take a series of pictures and post them - it should be easier for someone to guess what's gone wrong.

The video shows which wires go where. Prolly need to rewatch it.
One thing to be very careful with, is the front threading of the wiring up the center. If you don't thread the wires up correctly, the first turn of the handlebars will pull the connection apart. The wires in the kit have no extra slack for alternate threading directions.
My first guess would be this as the issue. Double check the wires from the knee pad to the handlebars. Do not reassemble without turning the handlebars and checking those wires.
If you pulled them apart after reassembling, you may have a blown fuse.

You may have another issue, but this is the most probable.

Edit: Robot also warns about the rear wiring being tucked up so it doesn't rub against the tire.

The issue that won't end!
I had my Vespa transported to a certified Vespa shop that cannot diagnose why my turn signals have no power. They did numerous checks to see where the faulty wires were and could not locate them. The service tech is thinking of a harness issue or some unknown electrical issue.
I am at my wit's end because the nearest Vespa dealer is a bit under 100 miles away.
I am wondering if I should reinstall the US pods back on. (Threw out the old ones and would have to purchase another set)

If power isn't going to the new lights, then there is no power to go to the old ones when you put 'em back.

Dealer says they can't find the issue sounds like they either didn't really look hard or don't know their wiring.

(1)LED's are polarity sensitive. You may have the wires reversed? This is assuming there is power.

(2)If you have verified the wiring is correct and connections are firm, then fuses and relay should be the next thing to check. A meter would be best to check with, BUT If you kept the old relay, you can test with it. The flash rate with be off, but at least you would then know.

Check fuses with a meter also. They can be blown and not noticeable sometimes.

If you have a meter, then you could check the wiring going to the relay when you turn on the signal.

Thanks Clampett!
If only the service techs I use were half as smart as you.

Experienced! And I'm not gonna tell you about the 3rd pod elimination I did when I couldn't figure out why the brake lights weren't working when I buttoned it all back up. Facepalm emoticon ROFL emoticon
