Viper Alarm installer taking my trailer break connection.

    Not 100% sure where to post this as it deals with towing but more so technical stuff with wiring, etc.

    I picked up my 09 Tacoma around 4/17/09 and had an alarm system installed (viper 5901) a week later. This morning I was going to install my trailer brakes, as I'm planning on towing a trailer within the next month.

    The problem is I can't find the towing harness plugin above the driverside kick panel. My rookie eyes spent about 45-60 minutes looking for the thing but complicating this was the alarm unit mounted here. I was thinking it was just in the way but instead I dug around even taking off the gray bottom dash panel off.

    I traced the appropriate color wires and what it appears to me is that they clipped the harness and used its wires to help wire the alarm system, possibly for shutting off the engine (it has remote start) when the brake pedal is pushed.

    Now this is upsetting if it is the case. Is there anyone who can provide me a detailed picture of which harness the plug is attached to?

    Thanks and any help is appreciated whether it be a comment about what to tell my alarm installer (Master's Car Audio, etc.) or about how to wire around it and splice back into the appropriate cables.

    What do you all think?

    Edit: Truck details almost forgot.
