shortening wiring harness
 

so ive recently ventured into two grand's a 94 and a 95. both are trail rigs in the making. both are also v8 5.2's i was wondering if anyone had ventured as far as triming wiring harness's .. i would like to remove all unnecessary wires and components. like a/c and headlights ( i plan to run completely different lights so stock lights aren't needed). also i've read up on the theft system and no there is a way to trick it but not remove it. is that a valid statement? any help is appreciated !!
