Good Afternoon Andrew
Thank you for the wire colour coding very helpful, however my car does not subscribe to the colour coding on the circuit diagram, I have assumed that on my car the White/Red is my Red, the Blue/Green is my Green, the Blue is Blue and the Black is Black, and with my trusty test meter have established that there was no supply to the Red wire and subsequently no output on the Green or the blue.
I have traced the colours back through the door to the main loom in the footwell and the White/Red (constant 12v) has been fitted with a scotchlock to obtain power for a F2029-89911 control box that is mounted on the cover under the steering wheel, and where they had cable tied the loom up under the dash the pressure had over time broken the White/Red wire (scotchlocks I hate them).
I have tested that the passenger door lock works with the broken wires held together, so now all that is required is to remake the connection this time it will be a solder joint which will subsequently be shrink wrapped, I have not checked the connections that George suggested as at this stage it is not necessary, but the photo's I have no doubt will be very useful in the future when lock failure becomes a issue so thank you for that.
The supply to the F2029-89911 is not really required as I understand, having googled it the unit would have controlled a parking mast which is unfortunately no longer fitted which is a real shame.
My thanks to all advice I am now off to fold myself in half to get into the footwell and solder the broken wires back together.
Incidentally in the unlikely event that anyone has a parking mast that they do not require please get in touch.
Many Thanks
Marc
