Ok found the connector behind the speedo. It has a brown and black wire going into the black connector (1 and 2). Am I right in assuming the black (2) goes into my sat nav black cable (4) and the brown (1) goes into my satnav red (3) cable. Do you just insert it in the connector and then solder it in and tape it? Lastly do you put the fuse holder on the red satnav cable (? position) and what fuse. I've heard 3, 1.6 and 1.5amp. Anyone have a picture of the fuse holder I'm looking for?
Thanks again, you can see how little I know by this.
