Daniel sells good parts. I use the same basic parts in the kits i put together.
That octane kit I can buy for $4 from the manufacturer. I've also taken one apart, and it is a "you get what you pay for" type deal. My craftsmanship, attention to detail and quality is light years better. My kit also hides easily within the factory harness retaining clips, etc., no gm wire covering. There are some design issues with the octane kit that do not address the problems with mopar charging systems. A single power feed provides no redundancy.
My kit also requires no modifications to your existing wiring harness, none. It's plug and play.
Pick your parts, pay your money.
