Wow, good info! Where did you get this IC timer, and does it have a part number?

building a relay based IC controlled timer to shut off full voltage to element after about 6 mins.

I would like to do this on my car. Did you run the supply voltage through a relay? What circuit under the hood did you hook it to? Could you show a wiring diagram?
Thanks
