How easy is it to install an overhead console in a Cherokee that didn't come with one? Would the wires and brackets already be up there or would I need to install those too? I know I'd have to get the temperature sensor. I've got a 95 2-door Sport - what other years could I look at for donors?

Thanks,
Ben
