Wiring harness

[Ricky]

So I have a 2008 Prostar that's here to stay so I'm always looking to upgrade things. Mine is the base model and I see that the more loaded models have things like oil, transmission, front and rear different temperature gauges. Also dump valves and fog lights. I know that I can simply add stuff like this but it would be nice for it to look factory. So the question is are all the Prostars wired for this stuff but you just have to dig it from the harness somewhere? I have a friend that there kenworth is like that. I have found a few 2008-10s with the ISX in my local salvage yard that are the really loaded ones and I like the dash and gauges set up. I think it would be a great upgrade but not trying to reinvent the wheel, lol.
