| Dual arcade steering wheel help. |

| fa001:
Not knowing which game your wheel is from I can not find the specific schematic. However here is a typical encoder. I would suspect that yours would be similar. |
| fa001:
Also on the IC pin 14 should be the +5 volts and pin 7 the Gnd. So you can check which wire out is +5 or Gnd by checking continuity to those pins. |

Thanks that should help. Have to do some tracing to the IC I guess. That PCB schematic looks very close to what I have. So if Im correct the 5+ on the opti pac goes to red wire, gnd to black, grey to x1 and brown to x2. Is this right? Really wish I new what game this came from..... |
| fa001:
That is where you need to look at the circuit board. But I would suspect that the heaver wires are the power wires and the thinner wires are the signal wires. So red and white (not black?) are power/ground and grey & brown are signal. But you should verify from the circuit traces which is power and which is ground. |

The nice thing is with these simple boards, all you need to get correct the first time is the power and ground. The 2 signal wires can be swapped if you get them backwards (the only problem will be the mouse pointer will move backwards). |
