I have just bought myself another K-50 5 speed.

I have noticed that there is 3 sensors on top of the box.

My stuffed box only has 1 (reverese light switch)

 

What are the other 2 sensors for ??? a neutral start switch ???

Manuals can start in any gear.

The other 2 switches are on 4th and 5th gear. You don't need these, ignore. They were used for emissions, and operate switches to make the carby more lean when cruising on the highway.

I am aware of this :ninja:

Check out the switches in the pic below

That was the only thing i could think of due to the positioning of the swithes :hmm:

Would it save fuel on long trips or just be a pain in the arse like most emissions control from that era ?

On a new car with a tight engine and everything hooked up, I imagine the switch on 4th and 5th gear would save fuel. The switch would operate one of those solenoids in the engine bay thats connected to the birds nest of vacuum hoses. I have had a tendency to rip all that stuff out and just have one hose from carby to distributor and block off everything else at the carby and manifold. But there would be some satisfaction in understanding all the hoses and having it work right, if you could be bothered getting a emissions test and working out fuel consumption. Something for a nerd apprenctice with far too much time on his hands I say. There should be a vacuum map sticker on the bonnet, or in the service manual.
