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

Right well i thought i would wright a how to so here goes

you will need.

JDM parts

A/C fan

A/C compressor



smooth pulley for 3gse

longer drive belt

A/C pipe work



A/C radiator

3 relays

heater duct assembly

evapourater housing

temp mixer cable



ambient temp sensor

cabin temp sensor



solar sensor middle one



Climate control unit



CC wiring



you will need the wiring on the evap and heater duct assemblies





if your car has Air conditioning you will need to swap a few things but for this mod take it as having no air con at all, the celica gen6 should have the wiring in place for normal aircon system so to make sure check for a few things

behind glove box should be a large multiplug above the blower duct and a multiplug below blower ducting both will be taped to the wiring loom in the respective places. in the engine bay you should check for a grey connector taped up near the diagnostic port and one taped to the wires on the radiator pipe from the thermostat, and last but not least a plug taped up near the left hand relay box.

once you have made sure you have them away we go!

remove the dash board



with the dash board out of the way remove the metal tubular frame as well, then you can get to work.

remove the following

in engine bay disconect the heater hoses and mixer cable

in the car remove the blower ducting and the heater duct assembly

with those out the way you can start the install

fit the JDM heater duct assembly thread the mixer cable through to the engine bay and heater hoses, then bolt it in and connect th ecable and hoses to their respective places.

next remove the blanking panel from the bulk head and then bolt the evap housing in place. in th eengine bay fit the JDM plate over where the Evap pipe work enters the engine bay.



then fit all the engine bay A/C parts just a matter of bolting them in place, compressor torque is 25nm and all A/C pipes are 10nm. fit the A/C fan to the radiator using the three bolts and then plug it in as well as plugging in the compressor and the pressure switch. thats the engine bay done. next up is wiring the beast in!

onc you plug all the multiplugs in you will be left with a few wires that need connecting.

the following wires just need removing from the CC multiplugs and then the relevant wire from the old system pushing in.

CC unit orange multiplug

GREEN - lights
GREEN/WHITE - lights

Middle white plug

BLUE/WHITE - heater relay



large plug at top of evap

BLUE/YELLOW - compressor relay
RED/YELLOW - pressure switch



the next set of wires need connecting to the following

GREY - ACC
GREEN/RED - Batt+
WHITE/BLACK - earths

multiplug below the evap



you will notice 2 wires missing from this plug we need to add them so you will need to remove the wires from the JDM plug YELLOW/BLACK & BLUE/YELLOW



clip them in the correct place on the cars plug and then connect

YELLOW/BLACK - compressor
BLUE/YELLOW pin16 of the 4th ecu plug directly below th egreen/yellow wire.

that should be all the wires connected but you will need swap a few wires over for the blower motor depending on how you have done it.



run 2 wires to the ambient sensor on the A/C rad and connect to the ambient sensor wires on the CC.
