DIY fuse power cutoff (no solder)

Having to crawl under the dash to unplug a fuse gets old real quick. But the ready made solutions can be so dang expensive. Upwards of $60.00 or so. Being of Scottish descent I couldn't bring myself to go that route. I'm not much for soldering but was going to give it a go UNTIL I figured out a way to do it without having to solder.

First step is to get a fuse the size of the one you need to switch. Mine was a mini automotive fuse. What your looking for is the spades that insert into the fuse box. Carefully use a side cutter to separate the two spades from the plastic.



Once separated, I found that with very little trimming, the spades slip into a blue wire connector. Trim the plastic on the connector to ensure the spades are free to slip into the fuse box when completed.



Use a connector tool to squeeze the connector onto the spade. Once done, strip one end of a low voltage wire and connect it to to open end. Do this for both spades.

Next step is to wire a new fuse holder with appropriate size fuse in line with one of the wires. The end of the wire gets hooked on one side of the switch. The remaining wire from the spades is hooked to the other side of the switch. When the circuit is closed (switch is on)the car will run as original. When the circuit is open (switch is off) the car is ready to tow.

The two spades can now be taped together tightly to simulate the distance required to fit into the fuse slot in the car. Take out the proper fuse and replace it with the your new setup. Test your device to ensure it's working properly then find a place for installing the switch. I used a black on-off switch I found at the local parts store.
