sPod Switch Panel and Relay Kit

I have one of these units that came with my truck, just wondering what exactly its intended for, I assume its to isolate lights and other accessories from existing wiring system? I have some aftermarket BX Built projector headlights that a local mechanic installed but have issues with them, only one side works and also for some reason, my high heater /ac controls stopped working at same time, wondering if they installed incorrectly and maybe causing issues, should I have these going through the Spod system to hopefully avoid issues?

 

all these types of switch systems are not so much to isolate new devices from the oem systems, but to make it easier to add new devices into the vehicle.

the general rule with any electrical gremlins is to first assume that something aftermarket that was added is the first cause. generally troubleshooting begins with disconnecting the aftermarket stuff first, and then verifying that there's still a problem.

it's unlikely that an add-on switch panel will have an effect on your hvac controls, though without seeing it, is still possible. also be sure to check the fuse panel under the dash, as well as potentially the one under the hood.

 

The Spod shouldn't have anything to do with what you mentioned. I doubt headlights are being run through your SPOD system. The spod should have a positive and negative running to it. Then you will have the switch panel in the truck. Then all accessories will run off of the SPOD. The spod provides relays for the attached accessories. The SPOD also has a minimum voltage cutoff, that will keep your truck from drawing down past 11.2 v (i am not sure if it is 11.2 to be exact, but somewhere around there). Spods do a really good job of isolating accessories from the vehicle power. With exception to winches (high electrical draw), most accessories can/should be run through the SPod unit. They are pretty well built and designed units.
