And....you don't own the 1969 GM Oldsmobile CSM which contains all the wiring diagrams?
There are minor differences between the 69 4-4-2 regarding wiring from all other 69 A-Body wiring.
Why not look here and evaluate the color wiring diagram for the 1969 V8 A-Body...
A picture of what you're viewing would assist, as well.

If the orange/ black and the pink are in a single 2-wire connector, they are for the gas pedal activated kickdown switch on a TH400 transmission. Cars not equipped with a TH400 (manual trans or TH350) still have the connector in the harness, it is just taped up out of the way and not used.

I think Tom (Loaded68W34) is correct regarding wire/function, but not the single two-wire connector; I also believe the OP (Jerryl) is correct regarding two single-wire connectors.

With no first-hand experience involving the TH400 transmission wiring; yet, having reviewed the wiring diagrams between 1968 - 1972 & recalling several previous discussions pertaining to the TH400 downshift solenoid note the following:

...the 72 TH400 will have a two terminal case connector...
JoeP >>> th400 kickdown solenoid check

Recall introduction of the TCS (Transmission Control Solenoid) beginning 1970. The delta in wiring exists w/ the introduction of the TCS where the connector wiring contained two single-wire connectors prior to the TCS and a single double-wire (two terminal) case connector post-1969.

Black w/ single Orange stripe is for the pedal activated (downshift solenoid) kick-down switch if equipped w/ a TH400 transmission - if no TH400 the connector is not connected but left up under the dash in the area of the column.
The pink wire I'm not 100%. I suspect it's either the IGN SW (pink wire) or the Parking & Low Brake Warning Lamp instrument cluster wire which feeds from the (if equipped) TH400 transmission switch; I suspect the latter.

End of day, I believe the 1969 (if equipped w/ TH400) had independent single-wire connectors. Hang tight, someone w/ specific/more knowledge will validate/invalidate.

Actually that would be Transmission Controlled Spark, used 1970-72. The addition of the federally-mandated EGR for the 1973 model year replaced the TCS system as an NOx reduction method.
