700R4 no wires inside

[RED1985]

OK guys I have another question. Our truck has a 700R4 and I hear people mention about the sensors and wiring inside the trans. Yesterday I dropped the pan to change the filter and I find that there are no wired inside the trans. I see the two sensors/Solenoids but not wires. The truck shifts fine and goes into overdrive and overall runs pretty good. It turns 1600 RPM at 75 mph. ( Pretty low but I plan to take care of that with a new rear-end and gears.) The truck was bought used so I have no idea what has all been done. I do see that the factory wiring for the Trans is not being used. It is still there and resting on top of a heat shield. New individual wires are run and connected to the Trans via a new connector.

Should I be worried?

I search the archives and found mention of rebuilt units that didn't require the wires but people mentioned it is still good to have them.
