Thread: 2004 Classic need help RE heated seats

That is from memory.

I also ordered 2 x switches.

So why do I need help?

Well I had a little sniff about, removed the switch panel etc to see what I will be in for at fitment time. The GREEN and BLACK switch plugs are there - great! but heading to the setas there are no looms are connectors. I lifted the carpet to see if maybe the loom would be hidden there but there was nothing.

The only other connector that is free is a brown female connector sitting above the SRS computer under the console. Do I need to order a missing loom?

G'day Alex.

Firstly, are you semi adept at reading/following wiring diagrams. If not, get good at this. Will make your life so much easier.

Next. Get a copy of RAVE, or for now, at least the wiring sections of RAVE for a D2.

Using RAVE, I can see that if the loom was there, that is from the console to the seat, you should have a brown 4 pin connector for the heat function. If you have electric seats, you will have a light grey 12pin plug loom going to the console(switches). I'm not sure if it's in the same loom, is there a brown 4pin plug end? It looks to me that more likely it could be coming out of the same loom as the yellow pre-tenioner plug on the drivers side.

RAVE will help you 1000x over because following the wiring diagrams and shows you the images in the electrical library that are relevant for your needs.
So, having the electrical library, pages 334-337, shows you the plugs, colours, where they come from(ie. what loom are they part of) ... etc.

But for the purposes of assisting here, you should have brown 4pin plugs on either side, pass side loom comes out of the tensioner loom, driver side I think too.
on the driver side, the black 2pin with red/white and black wires is the seat belt switch connector. Doesn't show one on the pass side tho. So on the drivers side you should have the yellow plug(tensioner), black plug(seat belt) and the brown plug(heater).

@AK83 . Thanks for taking the time to reply.

Got Rave yesterday. I can navigate enough to keep me out of trouble reading diagrams.

The only brown female connector I have is under the center console sitting on top of the SRS computer. There are no brown connectors under each seat comming from the center console(body harness).

Yes, you are correct. On the drivers side I have the yellow seat belt pretensioner wire that is connected and the black 2 x wire connector(that is not connectred to anything)

On the passenger side there is only the yellow seat belt pretensioner wire that is also connected.

I kind of feel that there must be a sub harness missing from the brown connector under the consolde that splits to either seat?

And also, Yes. This is a leather option manual seat car. 2004 Classic

Again, thanks for youtr help

Here is a pic or 2 of the brown connector above the SRS module behind/below the PW switches that I prseeume should have a subharness that splits to each seat?

My HSE has the heated seat switches inside the cubby box, don't know if that means the looms are in a different place.

My poverty pack 2001 manufacturer D2 had all the necessary connectors (and loom) for both heated seats and electric seats. I got some seats from a HSE and it all connected up easily. I just had to also buy the centre console switch cover plate designed to accept the heater switches and bought the 2 heater switches as.part of that (was a kit). Had to tell the BCU that it had electric seats then good to go. Cheers

The GREEN and BLACK switch plugs are there - great! but heading to the setas there are no looms are connectors

Hi, in the green plug there must be a blue/grey wire and in the black one a blue/pink.... follow those wires cos they are supposed to be connected to the seat heater element's plugs... also measure in those plugs if you have +12V on the light green/white wire.
