Can anyone recommend a fuse to tap for my radar detector hardwire? It seems as if everyone thinks it's so trivial, they don't post details. Thanks! As the weather starts to turn, I'm going to be driving the 4Runner more & more.
The ACC fuse would be a good choice. It gets power when your accessories (such as radio, dash lights, etc) have power.
I'm assuming that you are planning on buying a fuse tap such as t
his one from Amazon. I'm not certain which size we have (small or mini?).
When you install the tap, pull the fuse, and use a multi-meter to determine which side of the socket has 12V+. Do this by putting the meter on DC voltage, placing one probe to a solid metal surface to act as a good ground, and touch the other probe to one of the metal connectors inside the socket.
When you install your tap, you want the WIRE on the tap, to be on the same side as the metal connect that DID NOT have +12V when you tested the empty socket with your meter. The reason for this, is that way a heavy load or a short will blow the fuse, thereby disconnecting the power to the wire.
One other option, is to check any empty fuse slots with your meter. Check it with the truck off, and with the key in the "on" position. If you find and empty socket that is off when the car is off, and on when the car is on, then you can put a fuse in that empty socket, attaching the Radar detector to the correct side of the fuse by stripping about and inch of sheathing off of the + side, and carefully wrapping the bare wire around the CORRECT side of the fuse blade.
Some may scoff that this isn't a professional install, but I've never had problems doing this type of home-made tap. :nerd:
I know this advice isn't100% specific, but I hope it helps.
