has history has proved,.... there is a fine line between lazy,... and not knowing what you are doing , as you get the results... there's never enough time to do it right, but always enough time to do it over..
so I pulled out the screw, and just as I thought...they didn't even clean the paint off the frame... just grabbed the big bundle of wires, and screwed them to the frame.. for a system to work correct... you have to have the same amp capable ground as the cable size amp draw on the positive side....do you really think Thor engineered it this way.....NOT!!!,... total laziness on thor's employee's...stuff like this is what eats up the profit margine and drive's the cost up...
who ever installed the wire harness needs a time out without pay...
