If I were you Harry I would add a fuse block that is triggered from a relay total cost is around $20 and then you have up to 6 fused circuits you can use and best of all no worries of overloading anything.
Jconrad did a nice write up on how to do it but he wanted his hot all the time so did not use a relay.
