I've looked at about 4 pages of threads and searched every wording I can think of. My question is do i have to run my trucks factory computer to make my dash work? Plug coming out of firewall on passenger side.......is it needed? Or can I run my wires straight to the driver side plug?

I have my ls computer mounted on gender under hood with my fuse/relay block. All I need is (power, switched power, fuel pump and ground) then my engine is stand alone. I'm running nv4500 trans. Don't care about abs (don't think it really has it like the later model trucks) I've already done the solid axle swap.
