What is the Correct Diode Kit to Flat Tow a 2007 GMC Sierra 1500 New Body Style
Question:
Which wiring kit do I need to flat tow truck? The tail lights have two yellow wires going to each light, top and bottom. Do I wire them as one or? The running lights, brake, and turn signals use a two element bulb. Four or six diode kit? Wiring diagram would help.

Expert Reply:
I show that for a 2007 GMC Sierra 1500 new body style, you will need to use the Roadmaster 4-diode kit, # RM-154. Your truck has a 2 wire system (combined brake and turn circuit) so additional diodes are not needed.
There are diagrams on the product page, below the description, for wiring the diodes, and I have also included the pictures here. If the towing vehicle has a combined brake and turn circuit, you will use the first diagram. If the towing vehicle has separate brake and turn circuits, sue the third diagram and you will also need Brite-Lite converter, # RM-732.
