04 Tundra no power door locks, possible bad multiplex

I installed an aftermarket remote start on my truck, (works great) decided to hook up the remote door locks to the unit as well, (truck didn't come with key fobs) while checking for my door trigger wires I must have shorted something now my power door locks don't work at all, and I have to lock n unlock the doors manually. The left rear door will not lock at all like it has power holding it in the unlock position. When I push the lock unlock button at the doors the multiplex control module makes a clicking sound like a relay clicking on n off. Did I burn out the power door lock circuit in the multiplex? If so how do I go about purchasing a used one on ebay. Does the part numbers need to match, or will a unit coming from a truck with the same options package as mine work? Mine has a number 89221-0C060, haven't seen any in ebay with that number found plenty with a 89221- 0C030, 0C031, 0C041 and a 0C050 n a few more. Any help would be greatly appreciated. Thanks in advance
