I did mine a couple of weeks ago. You will need a new gauge, a tan wire and the sending unit that goes in the engine. Not sure which gauge package you have so I wont give you a part number for that. But I beleive the sending unit PN# is 174675. I used to have the system check where the temp gauge went. Purple wire will connect to the I terminal, Black wire to the G terminal, tan wire to the S terminal and the blue wire to the L terminal. Gauge is in the lower left of the pic. Sorry not very good picture. It maybe took 15 minutes to do.
