i can wire it myself but can i bring it back to chevy and have it done 16 years later lmao ? cause that's bull someone payed for an opinion that's not there

 

Anyone please

 

generally you just run new hot wires with self resetting breakers in the correct wire gauge
google 7 pin wiring diagram and make sure to pay attention to wire gauge and breaker size
Usually you can buy a 2 wire spool that is encased to easily run from front to back for both hot wires and just ground directly to the frame

BTW use caution when powering things like a RV fridge off the vehicle
My trailer fridge will kill a battery within about 45 minutes if the vehicle is not running
That will surely tax your alternator

 

Thank you for the response .... Yea I have no prob running new wire I plan on running 10 awg but don't know what size fuse/breaker .... So on a 6 pin that I have now (wires are just hanging out ) what is the light blue wire at the back and double white are both grounds? I know the thinker one is defiantly a ground
