Did a conversion on my 1990 Toyota pickup by putting in power door locks. I hand two actuators a pair of relays and a pair of 5 pin switches. How do I wire it properly. I get one switch to work than the other side trips a breaker. I tried different ways to wire the relays but same problem or they do not work at all thanks.

Take a look at the relay diagrams under door locks. Something like this should do it for you:

That’s the way I have it wired with two switches but with no alarm.

You can forgo the relays and wire both 5-pin switches in this sort of manner posted_image

The ground is passed through both switches at rest to the lock actuators. Upon activation of either switch the appropriate ground is interrupted and replaced with +12v power whilst the other ground sent to the actuator remains. This in turn causes the actuator to move in one direction or the other. You will have to correctly wire the switches you have to ensure switch 2 and the actuators are receiving the correct toggling output from the switch upstream.
