Looking for a Fridge wiring diagram SUper Custom 1997

I got a 1997 Super custom with a fridge between the front seats and a TV fitting on top. I removed the TV (at request of wife & kids) including a box where all the TV antena's collected. I now realise that there was more in that box than just TV stuff, because the fridge now doesn't work. There are 4 wires that connect to the antena box. 3 are power.
So, I'm after a wiring diagram that would tell me what was in the box I threw away.

By the wat the fridge was great when it did work. It has an ice setting which made ice cubes.

The fridge works off the A/C and heating system, well it did on my 94 SC,, there should be a 3 way switch that allows Hot, cool or ice setting. If you threw that away then trace back to where you unplugged it and get a circuit tester out and see what activates what.

Thank you Clive,
The circuit tester told me that 3 of the 4 wires in the box I removed were power. I could try connecting each of them in turn to the other wire until the fridge works, but something might blow.
It is odd that Toyota ran wiring into the box unless the box did something. Maybe it had a relay, fuse. I hope it didn't have some control unit. If I had a wiring diagram I could figure out what was missing.

If it is the same and runs of the A/C then it will just be valves to allow a small or lot of gas through, same with the heating.
www.toyodiy.com may have the switch, may help?

Clive,
My fridge sounds the same as yours, runs as an extra circuit off the AC with a solenoid valve openning/closing it. There must be a thermister in the heat exchanger to control the temperature. When I switch from ice to cool I must be changing it's set point. When the set point is reached I suspect there is a relay which switches the refrigerant valve off/on. Do you know where the relay is in your Hiace?

Not got the Hiace any more, sob.

Some above the drivers foot, and some behind a panel by the passngers right foot. Which is what should be marked on the cover.

I'm really regretting throwing away the box attached to the TV.

I went a bit further today. Started marking out all the wire colours into and out of the connectors. There was another black box within the fridge where the wires to the ice/cool switch seem to pass through. I wish I could find out what that did (as well as the now missing one).

Of the four wires that entered the TV box; one always had power, two others had power when the engine was running. I played around with connecting some of the wires together to see what would happen. Maybe get power to the Fridge. Well, the AC stopped working and the speedo, tacho, all the instrument panel, except for the radio stopped working. The Transmission was stuck in P. I now know where all the fuses and relays are, but it scared me that I had blown it up. I'm back to normal now and I'm not playing with wires until I know what they do.

here is a wiring diagram from a landcruiser console fridge this may help?

Thank you. I'll check it out.
