New 09 Truck Snow Plow Prep ?

[425EXPEDITION]

as part of the snow plow prep package it says: SNOW PLOW PREP PACKAGE includes 15-amp power for backup and roof emergency light.

in the manual for the aux.roof mounted lamp it says it is fused at 30 amps.

my questions is,is there an additional fuse set up for aux.back up lights(15a) ? if so does anyone know if the truck is wired for them ? just want to know if i have to run wires for back up lights ?

another question,what is a good place to pick up key-on power to feed relays for accessories ?

 

thanks

this is on a gmc sierra sle 2500hd ccsb 4x4

I think it might be easier just to tie into your brake harness for reverse wires, then hook lights to that. Get yourself some LED's for back up lights. I have them in my tail gate LED bar and they work really well!
