I took my truck to Firestone for a Emmisions test and failed due to my odb scanner not getting power.
I had them check the issue out and found that I had a lot of corrosion on one of the modules that connect under the fuse block. They told me they could not fix it unless I bought a whole new harness which would have costed me 2500. I told the to F off and have been working on this issue at home.
I took of the fuse box and found one of the modules c3 I believe fully corroded. I found 3 wires completely un connected to the module. This is a 42 pin connector and I am having trouble figuring out where these 1.5mm red wires go. I did go on the mopar connection Website but it’s not even showing 3 red wires for the c3 module. Does anyone have a better understanding of each module under the fuse box. There is 4 rectangular ones, ones green, blue, gray and black. The blue one is the one I’m having the corrosion issue with and I am trying to find a home for the 3 loose red wires that where not connected.
My obd doesn’t work and my volume to my radio. So I’m guess two of those 3 wires may be the fix
My truck is a 2017 ram 1500 3.6 l flex fuel.
I cleaned the whole blue connector with some corrosion spray and dialectic grease. It looks great now. I just gotta get these wires connected. Please if anyone can help I’d appreciate it.
The picture I added is a picture off of eBay and it’s the exact same set up as mine. Just an fyi if it helps.
