The kits on ebay you can get for like 15 bucks. how are these in quality and also are the wires long enough to actually place them where you want and not just go straight across the engine bay? These seem like a good deal? i think it would be easier cause it has pretty much everything in it. I dont have a crimper or a heat gun or anything like that...

 

those wires. on ebay are pretty good...
its good that they all go from the negative to the grounding points..
and i'm pretty sure they'll reach all the grounding points

there is a write up on vqpower.com

Make your own.

 

They aren't soldered and they aren't cut to fit. That plus the spider web look generally makes them a messy looking install IMHO.
