2018 RAM stock as a rock until now.

I purchased a RaceME Ultra tuner, EGR delete, and DPF exhaust delete.

As far as I have gotten, I installed the tuner because it keeps throwing an error code of 15012 or 12202.

I have checked the continuity on the RSA cable, and it is ok; it is plugged into the correct plug under the hood.

The only help RaceME has given to check for broken wires, my conclusion is if I have both green lights on the com box and sd card emblem, then I have communication there, and if there is continuity from one end to the other on the RSA Cable, then everything should work.

Can anyone tell me where the other end of the unlock plug goes in the factory harness?

I am not sure what else to test.

Any help would be appreciated.
