I was helping a buddie install a few DEFi gauges on his STI and we lost the little white plastic connector for the oil pressure wire to the controll unit. ITs a small 2 wire white plastic connector that plugs into the controll unit.

DOes any one have a extra one, or know where one can be purchased. He called the place he bought the gauges from and they said all they could do for him was sell him the complete wire from the sender connector to the controll unit connector. For the low price of $50

 

I had to buy a longer wire for my defi set up..horsepowerfreaks sells the wires call them up. That is where I got mine from.
