Are you like the countless LS swap guys out there, trying to go fast on the cheap and dirty? We get it. We love a great bang for the buck, but sometimes, it can be difficult to make it all come together when your pocket is full of lint. One of the key factors in an LS swap, with its proper in-place fuel-injection system (carb, really?), is the engine harness.
Sometimes you can get lucky at a yard or when you buy a used engine off of a scrapper online, but more often than not, it’s either pretty-well friend or MIA, entirely.
So what do you do? You give the good folks at BP Automotive a call!
