I drilled 4 - 1/4" holes through the new rear window seal with my dremel tool. I then put silicone on the female spade connectors. Used a c clip expander tool to spread the 1/4" holes and the spade connectors slipped right through. No need to cut and reconnect the spade connectors or remove the factory wiring to feed the wires through.
Let's see how the glass install goes!
