Those TAC modules are a booger, they changed the service number about every year. I have never heard of telling what year model the wiring is by the PCM connectors but ok I'm sure thats a thing. I know some I see are red and blue, I think the 04 model I just did was red and blue. But I don't pay much attention to that sort of thing. I have been told that you really don't need to mix and match that TAC stuff so I try to keep my pedals with the tac's when I junk one out.to avoid confusion. Jim
