AMP power step wiring for 2025 RAM 3500

[Omohundro]

I finally finished up my install yesterday. I had a white wire not tan on my 2025. Everything is working perfectly. I did use the ground on the left fender next to the battery, it’s a 10mm bolt.

Would you take a photo of the wires and taps that you used?

My steps on my 25 3500 are still not working correctly. I currently have the blue OBD wire connected to the white wire circled above and the white OBD wire connected to the blue with white stripe. The only thing I have to do is connect the ground somewhere else, currently connected to the battery. In the pictures above is that a tan wire on the bottom left?

definitely connect the ground wire to a body ground. I also connected to the battery negative. tech support at AMP said you MUST use a body ground.

This is the current connections.

This is the current connections.

It does not look like you have a good connection on that blue wire with the positap. I would take it out and make sure the wire is centered in the groove and tighten right down.

Is that the correct wires aside from the connector?

Yes that looks correct.

So the connector was junk on the blue wire, I got a new one and it seems to be working! Great call on that connection looking bad.

no problem at all, if you need help once your ready to install please reach out, after living a breathing this for 2 straight days I feel ready to assist ! since your's is a 2025 it should follow the instructions.

I still don’t know what to do with the yellow/black wire, and the yellow wire coming off the AMP supplied harness.

That goes to your OBD port module.
