Here is a link showing a way to connect a inexpensive 4 pin relay which enables a low amp 12v to grd circuit to activate a high amp circuit...

You can get one of these relays for under $5.00 however the install requires some experience with wire connectors and soldering to avoid problems with shorts. Care should be used in picking a open location to mount the relay in a accessible and clear area under the hood. Not under the dash.

The illustration shows the bosch 5th pin 87a which is not needed for this application...

The pigtail wire harness that hooks to the OEM switch is marked A-B-C . The switch comes in two pieces. The switch & the pigtail wire harness. The switches were $27 each at the dealership. The pigtail was $35 each at the dealer. I found the pigtail on line for $16 each. Just Google GM part # 12101864
