need power to plow controller
 

i have just installed a western plow to my 99 silverado 1500 and im not sure where to tie the controller power wire in under dash. needs an accessory wire capable of carrying 6 amps in addition to existing circuit loads and is controlled by the ignition key switch. how do i locate this power source?
thanks.

get the manual for the '09 and read the last two pages... I believe it is the same as
