I am trying to install a Electric Life keyless door lock kit, I decided to pre wire it so I can test it rather then mess with it when it's in the car and I am glad I did. Needless to say is doesn't work the wiring schematic and trouble shooting are a joke, I went as far to install just one side and then just the rear still no go, when I hook up the power lock energizes either full in or full out no response from the key fobs to cycle so I am trying to figure out how the relay works to see if there is something crossed but I do not understand the relay diagram hoping someone can help me out

 

Looks like it is actually two single pole single throw (SPST) relays in one package. When pin 2 receives a ground, the internal relay places +12v on pin (M). Same thing for pin 3 and (2M). Hope this helps.
