Add a battery switch installation

[Ruck0199]

I have a 3.0L merc. Trying to add a second battery and switch/ACR. Blue Seas #7649. The instructions for installation of the switch calls for a wire from house fuse panel (house power) to the switch. Where do I find this wire?

In reality, you remove the wire from it's existing location and move it over to the switch

Thank you for the reply.
My issue is that I cannot find the house power wire in order to remove it from its current location. I think it is red/purple wire attached to 90amp fuse on the starter post. There is also an orange wire coming from alternator attached to this fuse.

If you have an existing battery switch, it should be connected the ACC post on the back of the switch
