AUTOMOTIVE wiring can be a real head-scratcher at times. Even seemingly simple tasks like wiring in relays can prove to be challenging without the right know-how.

Scotty had wanted to blow up the old airbags from the Barina for a while, so it was time to put his wiring to the test.

The results were as expected, aside from the surprisingly bad smell, which required the use of face masks for a proper clean-up.
