Could it be an idle load compensator,for an A/C equipped vehicle? My 82 Caddy 1.6NA with A/C has provisions for 2 of these . The PO must have removed them,but the mounting brackets and electrical connectors are still present.Looks identical to the pic. The 81 Caddy 1.6NA w/o A/C that I used to own didn't have this setup. Both Caddys had upshift lights.
I'll check my caddy this weekend and see if I get power to the connector with the A/C ON. I'm wondering if these are still available,as I would like to replace mine,which are missing. Currently- My a/c needs a charge,just enough in the system for the compressor to run,but not enough for cold air. Hope to get to that soon.
You guys just gotta buncha wacky crap with swapped clusters all over the place is what i think ! lol j/k
The tranny reverse switch wiring/plug would tell whether it was factory upshift - in most cases - few would probably upgrade the wiring for the upshift if they were just swapping clusters for whatever need. (bad gauge, bad odometer, bad clock, lower mileage at resale, etc...)
Downgrading away from upshift would be easier to do, and maybe harder to detect.

That is what's up with most of them.. I have to wonder if it could have been a wacky dealer installed option or something.. The particular '80 I'm thinking of has it all.. It was a pretty top of the line Rabbit too.. Just about every imaginable option, a a few dealer add-ons as well...
Checked the VIN against the title. Same numbers, Car is listed as 1981. Checked pins on Reverse switch, 2 pin setup.
Guess I just have the newer dash component with a spare bulb waiting for use some day.
Would have to install components to get light working. Not a necessity, I can listen for the rattle and upshift.
Thanks for the leads, DAS
The Silver 82 Jetta Diesel i'm parting came with upshift indicator, electrical switches fore and aft on Inj Pump linkage arm, and 4 pin reverse switch.
Its also a factory A/C car.
