Now on a separate note - trailer wiring.
The 13pin euro connector on the Passat is supplied with an adapter to 7 pin flat for Aus.
Of the 13 pins, 7 are drawn from the connector (13pin connector pin numbers):
1. Yellow L/H indicator
2. Blue fog light
3. White earth
4. Green R/H indicator
5. Brown R/H side tail lights
6. Red Brakes
7. Black L/H side tail lights
1, 3, 4 and 6 are straight through connected to the equivalent 7 pin flat same colours.
2. Goes to the Brakes pin 5 in the 7 pin flat.
5 and 7 from the 13 pin are each fed into a IN5404 rectifier, and then joined together and connected to the 7 pin conenctor number 7 - which is for tail lights. The rectifiers have a reverse impedance of 1.7kohms.

When my trailer is connected to my car, the car sees a bulb out L/H trailer tail light. Apom's car does the same with my trailer, with either his adapter or mine.
My trailer has a resistance between pins 7 and 3 (just measured trailer off between tail light circuit pin 7 and earth pin 3) of 2.8 ohms. That seems low to me... ?
Any electrical gurus out there tell me what I need to do so that teh car does not see the tail light load as being a blown bulb?
