You just have to do the math to figure out how much power is available and what can be pulled out of these "taps". In other words if one of the "taps" is protected by a 20A fuse and that circuit is already pulling 10A, then the most you can pull out additionally would be 10A. Anything more will require a different circuit design.



You will also notice too that the newer fuse blocks are also keyed to mate up with the correct plug so that when a factory accessory was added it could not be plugged into the wrong spot.

Below are some plugs for factory accessories (Notice they include another connector to where more than one accessory can be plugged in and daisy chained off of the one spot from the fuse block):

Cruise Control Ignition 12V Fuse Block Plug:


Cruise Control Lighting 12V Fuse Block Plug:


Rear Defroster Accessory 12V Fuse Block Plug:

Thanks, this is great info, I didn't know about the factory accessory harness keying.
