I have an MY01 and I just picked up an MY02 defroster harness and center console (for the switch) from another member. I have the harness all hooked up to the plugs under the panels behind the driver seat, and I also have the hardtop plugged into it as well. When I push the defroster button, it doesn't light up, not does the defroster itself work.

I was reading that I need a relay. Where would it go and where could I get one? Would getting the relay fix everything so I can finally get it to work? Thanks.
