I have a 2012 Mazda 3i sport the 2.0 automatic transmission. The TCM plug was cut off the wires and I need to figure out how to put these back together but there are four yellow wires three orange four black and so forth all the same and I have no clue which wire gets attached to the other. PLEASE HELP ME.

My only recommendation is to get the entire harness that connects to the TCM.
