Mike,
 
The probes are most likely from the Vision Micro System's fuel quantity component used in either the EPI 800 or VM 1000 engine monitors.  red = +5 VDC, black = ground,  and white = a frequency associated with how far the probe is covered with fuel (less than 20Khz with a minimum probe length of about 16 inches).  The system was calibrated by noting such frequencies at known fuel quantities and VM would store these on a ROM chip for use in displaying the quantity.  It is a very accurate system.

Please help me identify these fuel probes. One has the number 60 stamped
on it and the other has the number 70 stamped on it. It's off an older
360 kit that never flew. My guess it's early 90's.
Thank You, Michael Hamblett
