Reverse the polarity to get the actuator to move in alternate directions. 5 wire can vary, but usually. 1 up, 1 down, ground, +12V (Not the same as Vcc) The 5th pin can vary. In some systems it’s a feedback pin, some it’s a guide pin to prevent you from plugging it in the wrong way, some it’s an additional ground, and some it’s just a NC pin (No Connect). Most of the time it will be a feedback pin. Second it’s a ground. The auto down or up feature is usually aided by the 5th pin. In this case it’s a feedback pin but is usually controlled by an external module and not very much circuitary. > [@Post up any old school pics of current or old projects](https://forums.speedlife.net/t/post-up-any-old-school-pics-of-current-or-old-projects/1448/2): > > ahh k thanks, and last part of my question: > > how do the power door lock keyless kits work? it comes with 2 actuators and 2 remotes…does the remote send a signal to each actuator and it goes off? meaning, that when i install these power door lock kits, i DO NOT wire anything into the car’s electrical system except power and ground? IF so, how will this be compatible with an alarm system installed in the future? Two remotes will lock and unlock both actuators. You can have feedback from your stock S13 system to provide to your aftermarket alarm and vice versa but it is not easy. Lets just say I was 90% there with combining factory system with aftermarket alarm on Vlads S13 and then I ended up frying the Alarm system. Not one of my happier days, that’s for sure. --- _[View the full topic](https://forums.speedlife.net/t/power-locks-install/133341)._
