Guy's ,

Just installed LA Choppers Prime Apes ( 16 ") on my 2004 Ultra. After the installation my speedo , tach, & oil pressure gauge stopped working. All the wiring for the bars works just fine, & nothing was done to the dash wiring. Has anyone had any issues with there dash gauges not working ??? About to start pulling out my hair !!!!!!

 

I think there is a ground wire that bolts to the upper tree. That didn't come loose or you not re-install it? Sounds like a ground issue.
