Why do you disconnect the negative battery terminal first?

If you were disconnecting the positive + cable first and you accidently touch a metal part the vehicle you will create a massive short circuit with the fireworks involved. The wrench in your hand will become an arc welder. By disconnecting the negative - cable first there is no danger of this happening as touching a metal part of the vehicle will do nothing as you are already working with the ground. Always disconnect the ground cable first and then you can move to the positive cable without worries.

A perfectly satisfactory alternative is to use a generic battery cable of the right length connected from the battery to the starter motor, and a generic battery cable with ring terminals on both ends connected from the starter motor back to the circuit breaker/relay box. This alternative is an exact electrical equivalent of the factory part, works great, and saves a bunch of both time (ordering part) and money. Good luck!
