Wire kit fir tow

[David0725]

I have a 2011 chevy Silverado can anyone recommend a wiring kit to install to tow 4 down?

I used the Roadmaster wiring kit with inline diodes, it just installs using your own car lights and has worked well for the last 15 years until I gave the car away.

run a separate wire.

I recommend one of these Curt wiring harnesses. They have the diodes built in. For my application it was plug and play, but it looks like you would splice in the kit for your truck. Still much easier and fool proof than anything else on the market. This looks like the one you need, but verify make, model, etc.

next question, is the truck an automatic or stick? some auto transmissions can't be spun for a long time with out lubrication.

^ That's the easy button right there for lights. KISS principle.
Regarding transmissions, we can only wish GM still offered trucks with a stick shift in 2011...

If an auto trans, it must be a 4 x 4 to tow four down.

The steering wheel does lock so I put a quick disconnect on the battery. It's a 4x4 truck so I put the transfer case in Neutral

no electrical modification needed. It's a 4 pole harness.
things to consider, does the steering wheel lock ? if not no worries If it does, unlock it and disconnect the battery.

next question, is the truck an automatic or stick? some auto transmissions can't be spun for a long time with out lubrication.
