Temporarily wired fuel temp and fuel pressure sensor to G3x. Temp worked great, Pressure- not so great.
After reviewing wiring diagram and a call to UMA- the SteinAir harness was wired to 5vDC supply. UMA needs 9-12 volts. My mistake. Temp. wired a 12v to sensor- worked great. . It donned of me that I would need to switch Oil pressure/ Manifold pressure and fuel pressure to 12v.
Pulled PFD and MFD and GSU73. Pulled harness and removed pin 75. Need to remove pin 55 and tie in pin 75 to 55. No small feat.
