you can do new power and ground for the battery in the engine compartment...the big three as its called...

Use the the $30 for s**t you hate buying, but need like wires, fuses, etc...
I hate buying crap like this because it is so marked up and expensive, but yet you need it. If the $30 is good for just that day, don't let the money go to waste.
If it were me I'd buy wire for the BIG 3 Upgrade and connectors
