Default Hyperflash harness issue/resolution

This is just an FYI really. The hyperflash harness and led setup is pretty simple but I did run into a weird issue that I wanted to share.

Got some led turn signal bulbs, normally led bulbs are polarized and only work one way, so with the install I plugged them in and they were on first try, lucky me! So I installed the hyper flash harness and as I hit the turn signals all hell broke loose! Every light on the car is flashing, dash included. So as I'm doing some research on this and finding some people with similar issues I decided to test a few things they mentioned. When the lights were down and off, everything flashed crazy and when the lights were up and on, the left turn signal stayed illuminated while the right side flashed. This led me to believe there was an issue with that bulb and after flipping it around it solved all the issues. (turns out these particular bulbs were not polarized and worked regardless of plug spec)

Just a little FYI if someone has a similar problem, I didn't find much apart from rooting the issue to the harness itself. Maybe this will help someone in the future!
