Question:
I have a 2003 chevy e3500 blue bird bus that i need to put a 4-flat trailer harness on. What do I need to wire a vehicle with separate brake and turn signal circuits?

Expert Reply:
Since you have separate brake and turn signals you will need a converter to add a 4-way to your 2003 Blue Bird bus. The Curt Upgraded Circuit Protected Powered Tail Light Converter # C56496 will adapt your 3-wire system to a 2-wire system so it is compatible with trailers. You will also need the # 55151 to complete the installation and possibly additional wire with # 12-1-1 depending on the length of the bus.
