Positives to Accessories

Hopefully this will help someone out, as complete notes & videos online do not fully explain or at times they leave out some part of importance. I have watched many videos and most times the host's ego's can get in the way or they fail to get their point across clearly. However; they do mean well, only one does need to get the job done. As egos goes, I think everything has been covered, let me know if my effort has failed to get across. ;)

Note: I have not added all of accessories to the fusebox or to the switches for obvious reasons, as the dash panel needs to be reinstalled onto the vehicle first, for routing, connect/wire to the appropriate already installed accessories. Hence the non-wired, yellow unused coloured wire connectors on the fusebox and not forgetting the switch 'positives' also need their connections on the three dash switches to their appropriate accessory.
