Installation was tricky but that's because I removed the spare tire and installed it in the space under the van. (crawls down the driveway) It worked out pretty well though. I had to order a 25 foot 6 gauge cable to connect the power supply, other than that the kit had pretty much everything I needed. I had 3 beeps so I ordered a 12v solenoid and installed it. Super cool rig for street racing. Let's hope the components survive where exposed to the elements. Will update if durability is an issue.
