Vaccum tube ID help
 

I have a 1986.5 TOYOTA SUPRA . I'm having a problem with my heater it does not work. I noticed that it was broken the winter after the car got a new engine put in. The car went to 3 shops including the one that put the engine in and none of them could fix it. The heater control valve is working. I thought it may be the motor on a air door. but I was looking around and noticed that both connectors on a vaccum swich (located near the thermostat on the radiator) were broken off and there were no vaccum hoses going to it. I found a pic of the swich online. Could anyone tell me where the 2 vaccum hoses go to?

Its the one on the top left

My heater vacuum line connects to a tee coming off the Cruise Control vacuum motor. If the vacuum switch is broken, like mine, by-pass it, and hook the vacuum line directly to the vacuum motor on the heater valve. Works fine for me.

Update
 

So, I still have not quite figured out where the 2 vaccum hoses that come off the thermostat housing BVSV go. Mine are missing and I can't figure out where they are sposed go or if they control the heater. As seen in Picture. Any help would be appreciated.

Looks like they connect to the vac and charcoal canister. We don’t have charcoal canister in the UK, so ours are capped off.

your switch is busted,
take hose # 88690C pull it from the bottom of the switch , and plug it into the the top of the like you see in my picture from the post above. when you step on the gas the value will open and you'll get heat .
