Once you got the kit, did the construction warrant the price? I mean 18g stranded is not gold...? I suppose I'm a little biased toward DIY as I play with 24/26g wires all day.
Honestly, the kit seems very complete. It’s got various connectors and detailed instructions for each component.
For someone with some electrical knowledge (me), but no experience wiring a car, I think it will be worth it.
I don’t doubt for a second it would have been cheaper to buy wires of the right gauge and color myself and follow the factory diagram, but I’m not quite experienced enough for that.
