Has anyone experienced a problem with their tach and coolant temp gauge sweeping when they turn on their blinker. Either side, doesn't matter. Along with this, both front fender side markers flash along with both cluster indicators. I changed the icu on the ball of the fuse box and checked the grounds.

I will post a video tomorrow if this will help

 

Can't figure out how to post a video. I did perform a wire tuck on the passenger side. If a ground was hooked up wrong, wouldn't both front blinkers react the same?
