After putting DRL Hamstar unit in, tail lights and dash lights are out.
I did not put it in, was done at the shop that did OoP.
What could be the cause?

A blown fuse....bad connection. Blown DRL module

You could take it back to the OoP shop and have them fix it under warranty.

I was thinking of doing this.
Wasn't cheap.
