2 extra wires at ECU

I just removed the cover of the ECU on my 75-280 Cali model, and

there are 2 white wires..with bullet connectors...coming out of the

wiring harness, at the 35 prong connector.

They are not connected to anything, and by looking at the FSM

wiring diagram, I see them listed as #11 Control Unit, and #26

checking terminal.

Does anyone on this forum know their function ? I can't seem

to see any mention of using them in the FSM nor the 75-76

EFI manual. Some Datsun dealer dianostics ??

Just curious....and yes they seem factory original to the harness.
