This is a design improvement over the original switch with the washer activator that pokes out the back. The activator is now internal.
The switch has the connections for the 3 wire plug, the keyed red wire plug, and the yellow wire for the washer fluid pump.
I did have to enlarge the dash hole a little bit. The shaft was just slightly larger then the original switch.
Took about 1 minute with a dremmel.
