number. For example the wire from the lube oil level sensor switch to the
input of the cnc control might be #537. If you look at the wiring inside the
electrical enclosures carefully, you'll notice that each wire is numbered
with little sticky labels wrapped around the insulation near each end where
it terminates. If you can find #537, that's the wire! Some signals, like
24Vdc common might be used in a lot of places, so a lot of wires will have
the same number because they carry the same signal. In a Bridgeport this wire
is #39 and there are a lot of them. The actual point to point wiring scheme
is up to the builder and can only be ascertained by inspection.

enclosures, plus scan the schematic we might be able to give you some
direction.
[Okay. I'll do that- I should have it uploaded next week sometime.]
Be forewarned, this is a pretty complex endeavor if you are not
comfortable with electrical/electronic type work, but don't be too
discouraged either!
