If you can add factory locks, you can always get universal power lock solenoids and wire them up yourself. Thats how i did my car. The solenoids were about 9 bucks each and i just pluged them into the alarm. Before i had the alarm, i used a double pole double throw momentary switch, setup for revers and forwrd polarity and that worked perfectly also. Depending on the alarm you cant have a switch in place because it will fry part of the locking module if you use the switch. Trust me on that one.
