If you only had an N/T oil pressure idiot light before, how could you now have an oil pressure gauge that is working by only changing the cluster Or did you install a new oil pressure sending unit? N/Ts only come with a sending switch that provides a ground path to the idiot light when oil pressure is low. Turbos come with a sending unit that provides a variable signal based on rising and falling pressures. According to the wire diagrams they don't use the same pin-out on the gauge cluster either. I'm curious because I'm doing some custom gauge installation as well. I'm trying to optimize the factory options avaible from the GSTs and the Avengers.
