Gauge issues

I installed the first compliment of gauges when I bought the car the boost and A/F work fine the oil pressure however didnt work. After the install none of the stock aux gauges worked either. Brian installed them he used what he said was the stock oil pressure sending unit wire(white/pink) however when I took it apart tonight I saw 3 white/pink wires. The ones he had used gave nothing so I reconnected them to their rightful pins and the fuel gauge now works however the charge/discharge and temp still do not. The stock oil pressure has no sending unit so I would not expect it to work and the boost is run off the stock boost so again I do not expect it to work. The third pink/white wire(second pin on the top from the left) provided a believable reading(about 60lb at idle) so I spliced it into the wire. After putting the cluster back in I started the engine to test the gauges and the oil pressure jumped from 0-100(the end of the range on the gauge) constantly it didnt change with engine RPM or load. Has anybody had a similar problem? Im starting to believe the sending unit is bad.
