Good day, I'm new to this forum and also new to GM trucks having owned Ford trucks in the past. Great source of knowledge located here!

I recently purchased a 2007 2500HD Silverado(new style) and wish to add a low cost theft deterent device to the truck as I have done with my previous trucks. With the F150s I placed a switch in series with the fuel pump circuit and would turn the switch to off when I wanted to cripple the fuel pump. The access to the fuel pump circuit is in the passenger door panel where the crash impact fuel cut off switch is located. My question? Is there a similar cut off switch in the Silverado and if so where is it located?

Also, does anyone have a source for hardcopy service manual, especially a wiring diagram?

Thanks for your assistance

 

Anyone?
