DEI 528T to Open Garage Door

I've searched and searched and I can't find the answer to this question. I want to wire my garage door opener to open my garage door using my headlight/bright switch. I figured I could just tap the bright power wire and use a relay to simulate pushing the button. That's all fine, I flip the switch and the garage door opens. The problem is that when I leave the brights on driving down the road it leaves the opener "on". Can I use a DEI 528T to do the same thing but shut down after a few seconds? If so can someone tell me what wires on the 528T go to what. I know with a regular relay it looks like: 85 - ground 86 - Tap into the high beam wire 30 - one of the leads from the opener 87 - to the other lead from the opener What does it look like with the DEI unit, or any other ideas? Thanks in advance.

No one?  I know I can't be the first person to try to figure this out...

Thanks for the reply. To answer your question, it's a '06 H3. I don't know much about these relay's. Will it do what I want it to do or do you suggest another route?
