Very easy to install well worth every penny

Love the unit and especially the long leads it allowed me to put the unit in the space behind my seat instead of the dash or engine compartment. I have a 71 Corvette and I like using this unit to power non-factory equipment like the LED headlights and the stereo/amp. I replaced the wiring but wanted something I could put in the car without altering the factory wiring harness so I can modernize the Vette a little.

you honestly cannot make an install of a relay any easier. directions are clear, every wire is labeled, and the kit includes everything you would need. Plain and simple, a first timer could install this with confidence. can and will buy this for future projects

You can buy a relay harness for about 4 bucks. A breaker is what, 5 bucks? Some wire, Let's say $10 bucks. So that's at most $27. Painless sells this for $100 more than you can put it together in minutes.
