This is how I would expect it to be wired.
I don' think you can wire 87 and 87a at the same time.
one is on with no power applied, the other is on with power applied.
I think you wired it a bit backwards.




Whats being done is a little unconventional but it works...87 & 87a are providing power to diffent paths to the motor... At rest (unenergized) it provides a path to ground...When energized it provides power...Here's a schematic that is actually for power locks doing the same thing...
