2010 Ram 3500 Custom Switch Wiring Install
Accessory Adding Made EZ With SPOD
Having a Jeep is easy. A gajillion companies make stuff for Jeeps. But what if you want some cool Jeep part for your other 4x4? For example, we wanted a clean wiring setup and a set of switches for the accessories in our ’10 Ram 3500 truck. We had seen the Spod power distribution and relay box on many Jeep Wranglers and even some Toyota Tacomas and FJ Cruisers, but nothing had been developed for our big 1-ton Ram adventure/work truck. We decided to take the problem in our own hands and build what we wanted. With the help of Spod, Viking Panels, and Western Fabricators we ended up with a clean, simple, and effective wiring solution.
Adding electrical devices to a new 4x4 is like playing Russian roulette. Since most new 4x4s run a CAN-bus system, where every part of the vehicle is computer controlled and communicates via digital signals, tapping into the wiring harness today is not as easy as days gone by. In fact, it isn’t a good idea to mess with the factory harness at all because adding additional loads to wires can set off fault codes and even shut down or disable certain systems.
For this reason we went with the Spod relay center. The Spod runs directly off the battery and feeds all the accessories while also monitoring the battery voltage so as not to overtax it. It does this completely separate of the factory harness except where it touches the battery terminals. We finished the install with a clean set of switches that blend well with the dash, offer day or night use, and keep our accessories within reach and our truck’s electrics happy.
