just had the under dash trim out of the wifes 320 and it has a obc gong fitted and wired up thing is the car doesnt have a obc it does have aircon and cruise but no obc not even the button on the stalk so why should it have the gong my car has no cruise or aircon but it does have obc but no gong altho the wire is there should i pinch it out of her car or is it needed for something else

My Touring has a gong fitted and wired up but no OBC,the original owner probably would have had to pay handsomely to have it "working".
If I were you I 'd be taking it out and fitting up to your car seeing as you have an OBC.

Do you have a didgital clock and outside temp gauge?

steal it

hi yes it has a digi clock and outside temp gauge does this mean it is a ice warning gong on the wifes .wonder why mine aint got one it aint got a outside temp sensor either it just reads -70f or something

If it has a digital clock and outside temp then this is known as a "6 button OBC" and has a gong that sounds when the temp drops below 3 degrees.

so that mystery is now solved wifes car has a 6 button obc can this be easily swapped for a 13 button like mine will it just plug in and work or is there a lot more to it.

thanks Paul

more or less as long as you get one with the full loom its just a case of connecting it all up paul

There is more to it.

You will need the 13 button OBC unit, the correct wiring loom, the relay box, the stalk and the horn.

the relay box and horn is only for the immobiliser function though if you want it, something i cannot get to work in mine for some reason, must have missed something out somewhere

I'm pretty sure there is a bridged loop in main wiring loom, remove this and the immobiliser will work.

You will need to remove the bridged loop and plug in the green/green red plug on the obc loom in place of it.

cheers, will have a look over the week

Alex if your car won't start after doing the above due to a problem somewhere in the obc etc...just replace the bridged wire plug.
