A quick request: Does anyone have the wiring diagram handy for a '70 E-body rallye dash?

I need to convert a harness for a friend - I have the parts that I need but my manuals are all packed away from the move.

IIRC the tach wire goes to spot 13 or 20 on the bulkhead harness - need to confirm that, colour and the connections for the oil gauge vs. idiot light.

Thanks in advance!
