This Diagram switches the negitive on pin 87 to the Blue wire on pin 30 when a negitive is applied to Pin 85. When no Negitive is applied to pin 85 the Relay keeps pin 30 and 87a connected.

Here is the same drawing modified with the Relay contacts drawn in so you can see what is going on.

I tried that digram and it doesn't work. When I wire up the relay the light goes on and off like always,but doesn't kick on when I unlock the doors?

Yes it did. Thanks I had to flip the wire that was blue to the red and the red to the blue. The way it was wired from the picture,the light would pop on when I locked it and go off when I unlocked it.
