![]() ![]() I encased the wire in small flex tubing the entire under van route to protect it and liberally used wire ties to keep it tidy and safe. The reason I went along the driver's side wires was to avoid getting near the exhaust and muffler and finding places to tie the cable to. I decided to run from the storage box to the driver's side where all the house wires run up half way to the front of the van then go across the van width, then up along side the fresh water tank on the passenger's side up to the weep hole. ![]() A bit of poking about and it showed there was a path for the wire to make it to the monitor location.Īfter determining I had a path, then it was back under the van to find the path to the passenger step well hole. Then I took off the trim over the sliding door that forms a pocket. Next was the plastic step for the passenger seat where I found a weep hole in the metal to under the van big enough for the cable and a small flex tube leaving a bit of room for water to seep out still. I started by taking off the plastic cover for the door pillar between the passenger seat and sliding door. I decided to try to put it on an upper cabinet right by the sliding door. I bought a 25 foot length of wire made up for the monitor so I had plenty of wire to work with. In deciding where to put it, I had two things to consider: visibility of the monitor and a route to get the wire to it. All the advice I found said that monitor needs to be in a very visible place so it is easy to see and keep track of how the batteries are doing. Once the shunt part was completed, the next step was to run the monitor wires from the battery and shunt to the location of the monitor. That took an entire, long day of work to complete. Then I used plenty of cable ties to keep them in place. Then, under the van to neatly route each cable ( labeled on each end to keep track of which is which) to it's destination. After getting the shunt cabled, I used wire ties to keep them tidy and from possibly shifting. I used red plastic hole protectors to keep the cables from ever abrading. Bent them and drilled 4 holes with a 1" hole saw for the cables to come in from the outside. I connected the cables to the shunt (the 2 battery neg to one side and the vehicle ground and inverter neg cables to the other side of the shunt. ![]() ![]() I got a scrap piece of luan plywood and glued it to the inside top of the box to provide a more substantial mounting area after painting it. I decided to mount the shunt inside the box to protect it from the elements and run the cables to it from underneath the van. The van has a big storage box mounted under the floor in the back of the van between the two batteries, also in underfloor boxes. I did not have room to mount the shunt in one of the battery boxes. It was larger than really needed but I had it so all it needed was a new connector for the end.įirst decision was to determine where to put the shunt. I used a piece of the old inverter cable I replaced for the shunt to ground. Since none of the cables except for the inverter cable would reach to the shunt, I elected to get 2 new battery neg to shunt cables of equal length (in case that helps). The monitor requires all the cables from the battery negative to go to the shunt and then an additional cable goes from the shunt to the vehicle ground. The driver side battery also had the negative cable to the inverter. Originally, my van had each battery with a ground wire from the van metal to each negative post. The monitor requires a shunt to be in between the battery negative and all other connections on the negative/ground side. I finished the Trimetric 2025-RV battery monitor installation in my 2005 LTV Free Spirit van with 2 house batteries. ![]()
