please tell me what these are????....also if you have any idea where the wires go that would be great also...

first pic is one from a 1989 na fairlane...3 wires




the second is off my 1993 eb2 "s" 2 wires



any ideas??

thanks

They look like the pipe connectors that connect the metal pipes going into the heater box.

Is the second one under the Washer bottle? if so, it is defiently for the heater box hoses, be careful when you undo them as some crap can come out of it and you may smell something

Sorry if i couldnt be of any more help

I believe that is the TX valve (or Thermal Expansion valve) for the A/C. It goes near the firewall, where the A/C lines come out of the firewall.
Dont mix them up between models, they are different. If it doesnt fit neatly, dont force it.
Better yet, leave it loose, and ask the A/C guy to make sure it is sealed before he gasses the system.

thank you very much...

im converting from manual aircon to climate control......i have worked everything out including the wiring but these are different and one has three wires and one has two...

so i needed to know what it was so i could try and find the wiring for it,...

thanks heaps

ok just had a look and cant find the words....Thermal Expansion valve....or ..txv......anywhere

is it known by another name???

You are holding the air con pipes not a wiring conector.
What are you actualy trying to do.
You have been told the valves are not compatable between models.

im trying to convert to climate control...(i have normate at the moment in my eb)

i have taken all the componets out of a na fairlane....i just noticed today as i took the heater box out of tha fairlane that this part was different.....

my first question was....What is this??

my second question was...where do the wires go that connect to it....

the failane one..(top pic) has three wires coming from it....(not shown as i have disconnected it)


the eb one is still connected but only has two wires...

i understand that people may not know where the wires go so that is why i was asking if it was called by another name as i have been through three different wiring diagrams and none say "Thermal Expansion valve".

so now my question is.....is it called another name other then Thermal Expansion valve or txv??

and/or does anyone know where the wires that connect to it go???

Its called a TX pressure switch. One wire goes to air con clutch and the other to a relay.
You will need to cross reference the climate control wiring diagrams from each model. If your car had air i would assume most of it is already there.

are you changing the airbox aswell?
Didn't think ya needed to do that when doin a CC conversion.

You dont but its done now so it has to be fixed.
