Let me first state my setup. I have the following installed:
OEM Clear tails without accessory package
Rear fogs activated with new switch panel
Ian's Auto Up Circuit with Auto front fog piggy backed to it
Diode brake light mod

Everything works fine except one thing. Only the drivers rear fog comes on when activated. Brake light mod works when rear fogs are off. has anyone had this happen to them? Is there something I should check? Should I take it all out and take it in for service? Help please!? TIA
