Climate control wiring Options

[Cavegod]

Hi all i am curently installing cauto climate control in to a non climate control car so thats climate control out of a 1994 jdm Gen6 Celica st202 and installing it into a 1997 uk Gen6 gt st202.

does anybody know where to get a wiring diagram for the auto climate control system as i can only find one for a Gen5 st182 celica.

heres hoping

Cheers Rusty, you will need to remove the trim around gearstick (just unclips at the back then the front, the trim around heater and stereo 2 screws at the bottom then just pull from bottom, remove the heater controls 2 screws and unclip the plugs at the back.

the wires i need to know about are as follows.

behind the heater control and lower down are three multiplugs attached to the heater box from left to right they are Black, white, grey. may be opposite if left hand drive.

on the black plug on the bottom row there is an orange wire i need to make sure this has continuity to the orange wires on the blue plug above and to the right(RHD) of the centre vents.

on the middle white plug i need to know if the green/red wire bottom row next to a grey wire has 12v with ignition off and also the grey wire next to it has 12v with ignition on and 0v with ignition off.

many thanks if you do this for me.

right first off sorry for not getting back to you sooner, I had a look around, I tryed to followed the wires (which go up in one lot) and I cant see where they go
got a couple of pictures dont think they'll help you though, but from the looks of your previous post you might already have it.

(sorry the loose wires, USB wire & that funny looking black right angle thing are a plug and play for my headunit)

just wondering did you have to wire those up or are they not part of it?




I also found the bulb I need to replace for the fan speed (lower left bulb) I went on toyodiy 84999-10530 that seem right to you guys?

It does. The wire runs up to that junction block and has its own pin. There is also a splice in that wire, about 150mm before the blue junction block. The spliced wire runs off to the passenger footwell on my RHD car. I forget where it goes after that but have some notes somewhere if you can't work it out.

on the middle white plug i need to know if the green/red wire bottom row next to a grey wire has 12v with ignition off and also the grey wire next to it has 12v with ignition on and 0v with ignition off.

The grey wire is ACC. It is 0v with ignition off and 12v with the key in the ACC or IG (I) positions. From memory it is N/C with they key in the ST(II) position but that's not imporant. I don't recall if it connects to ACC before or after the cig&radio fuse but could find out for you if needed.

The green/red wire is ECU-B. It is constant 12v and goes to the fused side of the 15A ECU-B fuse. Again, if you want to know exactly where the wire *should* terminate (as oppsoed to just splicing it into any convenient ECU-B wire) let me know and I'll try to find my notes.

Rusty: Yup, you do need all three of those sensors. From previous posts, it sounds like cavegod has them.
