Ok, so I have a KE70 pannel van. I'm not sure what gear box it is, I'm pretty sure its a K50 (cable clutch, etc.) but my main problem is my reverse lights are'nt working and I have narrowed it down to the sender in the box. Is the plug for the sender the one that comes from the rubber plug thing on of the box in front of the shifter?

Any help would be much appreciated.

Thanks in advance.

Edit: Found it, it was the switch, its not pushing in far enough I don't think.
