So yesterday I discovered that the little connection on the right on the thermostat housing broke on my 4k.

I don't know what it is but its like three cords maybe a centimetre in diameter that plug into the side of the housing through a little screw in plug thing, and the plug itself has snapped.

What is this for? And where can I get a new one?

 

Thanks in advance, Jake.

 

Note: will upload pictures when I get home from work

Sound like the vacume switch that changes the vac advance on the dissy depending on coolant temp.

chase the hoses through one goes to the dissy and 2 to the carby I think, If it is this yep you can run OK without it you might just loose some part throttle power.

Andy is right-

 

you can block most those hoses and the car runs fine. The only ones I kept were the vac advance and the charcoal canister.

So is it worth replacing
