VLED help?!

Bought some VLED’s from a member here and I have zero issues with that.

The lights I bought are the V3 switchbacks. First when they arrived USPS broke one of the lenses off in transit. Contacted VLED’s and told them the situation and that I even purchased them used from another person and they were absolutely top notch in coaching me how to repair it. Got it all put together and waited for the double sided tape to arrive to mount the load resistors. Got them put in and installed yesterday. Worked fine in the driveway and everything checked out.

Went out last night and got the “hyper flash” from the left blinker. Left light wasn’t on or working. Tried unplugging and plugging in all the connectors again and even flipped the socket plug around to see if that made a difference. Nothing.

is there a wiring diagram that anyone might know or have to check these out? I’m not completely stupid when it comes to using a multimeter but I’m no genius either. Is there’s places I should check for resistance or continuity between that are common problems?

Or should I just eat the $80 I spent and chalk it up to the experience of buying used electronics.
