Boost onto boost sensor that comes with gauge and t off...
Oil temp/pressure can either from a sandwich plate or adaptor where factory pressure sensor goes where allows x2 sensors in. As in factory and aftermarket. Temp can go into blanker plug front turbo on block using factory adapter you took outta where original one was at front if you get me.
Prob with these gauges is oil pressure sender unit is huge and sandwich plate may cause issues fouling sump. Defi senders are for example x5 times smaller.
