I hate wiring!! ...and have some questions.

What is the best way to splice very small gauge wire? Are there extremely small butt connectors or do I just twist them real tight and put some electrical tape on them?

Anybody know enough about the wiring in a 92 Suburban to confirm that the purple wires that run to the rear are for the rear window defoster?

Anybody successfuly wire electric seats? I am really hoping I can make these 2004 Bravada seats work.

Thank you, Jay
