The DSX Tuning flex fuel kit is the original plug and play solution to adding flex fuel on Gen IV/Gen V GM V8 vehicles. Use these kits to add the ability to run anywhere from straight gasoline to straight ethanol as well as reveal the true power potential of your setup.

Good Cable
Size: 2AWG 15FT + 15FT, Color: Red + Black
Work as intended. I used it to run some cable to a second battery from the first. If you're going to do that though, 100% have two fuses. One next to each battery post.
It's pretty heavy cable too, good stuff.

I think is a quality wire and affordable
Size: 2AWG 15FT + 15FT, Color: Red + Black
The wire is excellent; its thickness feels appropriate, and it appears to be high quality. I've installed it on my PV array, which delivers over 40 amps DC, and the wire handles this load well. MC4 connectors are not included but are pre-cut for easy installation, and I encountered no problems.
