Hi! Just got this old camper, and trying to make it ready for a holiday trip. Downloaded a service manual today, covering 1981 to 1993. Some useful info there, will have to replace a driveshaft, and this seems to be covered nicely. But yesterday I wanted to install a DAB-radio, and was poking around in the dashboard. I noticed 3-4 multiway connectors, see picture. Anyone now what they are for? Only one of them have one single wire connected. The downloded service manual have a "Pocket Mechanic Manual" with wiring diagrams, but i`m not able to identify the connectors. For the radio things are mostly ok, as there are already fitted ISO-connectors. Except that the red and yellow wire are connected together, I want to find a wire from the ignitions switch for the red.
