OK, gearhead community, we get it. You want to swap GM LS-series motors in everything—muscle cars, hot rods, imports, trucks, Jeeps, coffee makers, pinball machines, CD players, pipe organs, houseplants, etc. Problem is, after you pluck your LS from the junkyard, there’s a good chance its wiring harness has been hacked to bits. And even

You don’t have to be a wiring guru to understand the principle of an electrical relay. Quite simply, relays are essentially switches that can be remote-controlled. They work by using the principles of electro-magnetism. When energized by a simple 12-volt source, the magnet will either turn the electrical switch on or off. Want more information

Making a splice in a vehicle’s automotive wiring is a critical task, because you’ve got to ensure there’s a solid electrical and mechanical connection that will withstand the vibration and temperature extremes found in automotive environments. Often, these splices must occur in tight spaces where there’s limited access to the wires, which can compound the

[portfolio_slideshow id=37184] An electrical system is only as reliable as its components. One easy way to increase system reliability and performance is by using relays to switch devices (lights, fuel pumps, fans, etc.) on and off. A relay is an electro-mechanical switch. An electro-magnet (also called a coil) is used to pull a set of
