Stop Pulling Fuses to Flat Tow Your Vehicle
Do you have to pull ignition fuses from your vehicle every time you flat tow your car? Our RV neighbors Jay & Linda Clark drive a 2008 Saturn Vue and they did too. One day a fuse broke off in the fuse panel leaving them stranded and Jay had finally had enough. Jay & Erik got to work on fixing the Saturn and after getting things fixed, they decides to build a permanent solution to end the full pulling nightmare.
Today we are going to show everyone how we built a fuse relocation and switch box assembly designed to bypass the ignition fuse for towing. This switch box ends the need to pull the fuse, simulating what happens when you pull the fuse manually.
Before we get started, EVERY vehicle is different. Please consult the manual that came with your vehicle and the manufacture on the specific procedure you must follow to flat tow your vehicle. Not all vehicles can be flat towed and this article is not designed to help anyone flat tow a vehicle that was not designed to be towed by the manufacturer. You assume all responsibility by following these instructions. Now let’s get on to building! First, this project is for the do-it-yourselfer. If you are not comfortable with wiring, soldering and a basic understanding of 12 volt electrical systems then please get help from a friend who knows their way around an electrical system before proceeding. Ok let’s get started with a materials and tool list.
- Automotive grade switch
- 2 wire hookup wire/speaker wire (18-21 gauge recommended for most applications below 15amps)
- Heat string tubing/or good quality vinyl electrical table
- 2x extra fuses, same rating as your ignition fuses
- Hobby box – if you don’t want to permanently mount your switch to your car (glove box is a common location)
- In line fuse holder – this one doesn’t have a light when the fuse is out but it does come with a fuse assortment.
- Soldering gun with rosin core solder.
- Drill and drill bits (stepper bit preferred otherwise check your switch for what size hole you’ll need to make to mount switch)
- Multimeter (for testing circuit and switch after assembly)
Our video above goes into great detail on the actual assembly of the fuse relocation and switch assembly. Please watch this video and follow the instructions included to build your own assembly. Here is a basic diagram of what you are building.
