Vladimir,
I once thought my previous '84 900S had something disconnected when I saw some wires dangling near the throttle body, below the intake runners.
I tried plugging one onto the throttle position switch, and the engine (which happened to be running) died immediately! I disconnected the wire, post haste, and all was well after a restart.
If your '83 NA is like my '84 S (also NA), then some wires do exist in our engine bays (near throttle, especially) that were meant for Turbo gadgets (OK, items) which we don't have. Therefore, some wires "go nowhere," since the components they were intended to plug into aren't needed our NA cars. The SAAB engine bay thoroughly confused me until I came to that realization.
The throttle position switch is not a variable-ohm reading type depending on throttle position like in some much later 900s (with 2.1L 16V engines). OUR old 8V cars' throttle switches click closed a circuit when you floorboard the gas pedal--a.k.a. wide open-throttle (WOT)--to cut off the air-conditioner (if your '83 has A/C). Part of the throttle valve arm acts like a cam to raise and contact this switch. You can hear it click with engine off if you open throttle valve by hand. If memory serves me correctly, this switch has three spade lug male terminals, but only two are used (top and bot. on my '84).
[Side note: In 8V Turbos (only), the throttle switch signals the CIS computer to lock the air/fuel mixture Lambda modulating valve--driver's side inner fenderwell--on 75% during WOT at or above 3,500 RPM during some years. This gave extra fuel during hard acceleration/high boost to cool engine a bit and prevent detonation, too, I think.]
Also, there is a separate switch--on both 8V NA and T cars--which closes a circuit and "kicks-up" the idle speed if your A/C is running when you let completely off the gas pedal. This keeps the idle from bogging at a stoplight, etc. with A/C on. This switch is the isolated male spade lug terminal which the throttle stop screw contacts (driver's side of throttle valve).
So, if everything seems to be working OK, then I'd leave those wires alone. Just blindly plugging wires onto things could have bad results (as I nearly saw!).
I hope this helps!
