Hey all. I'm doin a coversion on my 03 reg cab super duty. I've got the interior out of a wrecked 09. Gonna try n put the newer style dash in my 03. My question is how much of a pain in the butt will the wiring to the gauge cluster be ? Will the new cluster be compatible with the old as far as lights and such ? I know the harness is different between the two. Has anyone done a swap and had to do wiring ? Any help is awesome
