I am installing a Clarion CZ300 into a boat that previously had no battery. On the 16-pin wiring harness I thought I could connect the following 3 wires to one positive lead to the battery. Yellow wire (memory back-up lead) - book says "connect directly to battery" Red Wire (power lead) - books says "accessory + 12v" Orange/White wire (illumination lead) - book says "connect it to the car power supply terminal for illumination" So.. Can I wire the above wires together to one power supply wire connect to a switch then to the battery? I know that the memory will not work once I flip the switch but I would like to flip the switch when the boat is being stored long periods. And the last question. I tried the above wiring setup and instantly blew the fuse when plugging in the head unit. The fuse is a 15A online fuse on the memory wire, which is interestingly the largest gauge wire connected to the 16 pin. Thanks for making it this far if you did.
