alirght so i have a wiring harness in the engine bay for a base model diesel no ac no outside temp gauge .i want to add these features ive got a wiring harness out of a v10 with these features is there a way i can possibly splice these in and have them magically work?the in cab wiring is setup up for ac and temp sensor. i hate wiring

I personally wouldn't even mess with a new harness, just add the three or four additional wires needed separately.
