Help wiring SV21 Cruise Control
|

I was at the wreckers today when I spotted a factory cruise control on an SV21, so I got the bits (what the guy said was "all the bits I need" (which I think he's wrong).
Need some help wiring...
First of all, I've got the actuator unit that goes in the engine bay, I've got the brake pedal switch, and I've got the main switch (that goes under the center aircond vent, sort of). I believe I'm missing (at least) the control unit, and the set/resume switch. Not sure if I'm missing anything else?
From this picture, I've figured that C is the vacuum pump, and B is the actuator (although the wire colors don't match, mine are WB, G and RY; in the Gregory's book it says WB, GB, RG). What is A?
I've also noticed that my Camry (wagon CSX) already has the plugs for the actuator unit (A, B and C) and a plug to plug in the main switch. Since they've put the wiring in for those, would they have put in the wiring for the brake switch and resume switch? I can't find it.
Also, where is the control unit, and where is the set/resume switch? I couldn't find them on the donor car...
Thanks heaps

Well... Could someone at least point me to where the rest of the bits may be, so that I could get them off the donor car (since I've already paid for them)?

Hehe, daily driver that does a lot of freeway driving 
Found the bits. Control wand was indeed one of the stalks. The lettering had all faded off so I didn't realise there were more functions on it than normal!
The computer is on the passenger side tucked behind the blower unit. Took me 2 hours to find it! Took the whole dash apart, found the central locking module (under the dash pad, above the glove compartment), couldn't find the unit so traced the wires from the switch 
My Camry (and all the other ones with power mirrors and central locking, it seems), has some of the plugs required for the cruise control (all the ones in the engine bay: actuator and vacuum solonoids, cruise control main switch) but is missing some ie control unit, brake switch, maybe set/resume switch. Does anyone know where the wires that are existing actually go? I was hoping that it was just a different loom that plugged in, but after taking the other car apart it doesn't look like it, it's all part of one loom. It's as if someone started making the loom for the cruise control, and then decided they were too lazy so just left the rest

Wow, so going to need an auto electrician to look at this. For a start, the wire colors don't match Gregory's book (surprise surprise). That's all ok (I wired up my 4AGE in my KE35 without knowing colors because those didn't match either), except the control module also has several wires of the same color... And I don't have a pin-out diagram for the module...
Does anyone have one? I was hoping it would say something inside (like the 4AGE computers) but I took it apart and there's nothing...
