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

Ok BSD here you go

here is my jdm compressor with the uk wiring plug and yes i am missing the 4th wire yellow/black it conects to a cylinder on the back of the compressor near the exhaust and then earths.



here is a pic of my throttle position sensor am i missing a wire?



ok inside the car now the big multiblock connector on the top of the evap housing

JDM



UK minus the red/yellow (pressure switch) and blue/yellow (compressor relay earth)



heres both the uk and jdm relay side by side both identical even part no.s



this is the pink/blue wire



it goes to here which i think is one of the three vertical connectors below the radio



as you can see that is where it stops



right that just leaves the multi plug below the evap

this is the climate control side female plug



uk male side



jdm male side



jdm and uk side by side 'jdm plugged in'



so as you can see i have 2 wires not connected the yellow/black (compressor) and the blue/ yellow which is 12v live and according to th ewiring diagram goes to the ecu 'ATS'

so if i connect the yellow/black to the compressor where does the throttle position sensor wire connect to as i only have the 12v blue/yellow not connected?

Mine is the same:


Here is the coil of wire ready to connect if needs be:

No. The blue/white wire turns out to be for cruise control. It goes through the grey connector vertically mounted at the bottom of the centre console, snakes around the driver's side of the dashboard, goes through one of the white connectors on the passengers kick panel and ends up at pin 19 (21 according to the wiring diagram - maybe I miscounted) of the green cruise ecu connector.

The fast acting relay:


The black connector at the bottom of the centre console:



The other side of it:



For completeness, the white connector next to it:




The grey connector joining the engine bay loom to the cabin loom - vertically mounted at the bottom of the centre console:


The other side of it:

I call this the black or white plug between the blower and the heater

this is the climate control side female plug

Mine is the same:

jdm male side

Mine is the same - yellow/black and blue/yellow not connected:

I think you can forget about the throttle wire until you come to do the cruise control.
