If there is one thing we like to do around here at Chevy Hardcore, it’s that we’ll hot rod anything we can get our hands on. It doesn’t matter whether it’s our daily driver, or the latest project car, we can’t leave things alone.

Such is the case with our project car Blank Slate. We’ve been working on the Camaro for a while, and as you know, the car now has a running engine. In the article Making Shocking Connections, we showed you guys what it took for us to completely rewire the car and make sure that there would be no issues because of old, worn-out wiring. Since wiring a car can be a tedious and daunting task, we took you through just about everything that was required to ensure that Blank Slate had an updated and reliable wiring system. But, we made some changes to the car since then.

Howell Engine Development makes this small section of wire harness for relocating the coils of LS engines.

As you know, Blank Slate is now powered by a 720-horsepower LSX engine. When the engine was assembled, just like when delivered from the factory, the ignition coils were mounted to the valve covers. In stock form, having the coils closer to the spark plugs means that the spark-inducing voltage has less resisted-distance of spark plug wire to travel. But, in cases like ours where the engine is not stock, and might generate more heat than when it was, moving the coils from the valve cover to a location away from the engine is not a bad idea. The problem that we ran into was that the wiring harness that powers each coil is not long enough to facilitate relocation. Luckily, that’s where Howell Engine Development comes in.

The Howell extensions literally took just a minute or two to install.

With the help of Moroso’s coil relocation brackets, we were able to remove the coils from the engine, and cleanly mount them on the inner fenders of the car. While this does clean up the look of the engine and get the coils away from a lot of engine heat, connecting them to the ignition supply source was another issue. HED takes the difficulty out of adapting late-model GM engines into classic Chevy cars by offering a plethora of standalone parts for making a daunting task of wiring much easier. This means that anyone—even with limited electronics experience, can install an LS into their car.

The extensions that we needed required the use of a gray connector (Part Number HC14), but if your harness uses the black connector, there is one available for you as well. After mounting the coils in their new location, the installation of Howell’s harness extensions was a simple plug-and-play process.

If you are—or are planning an LS swap into your classic Chevy, you really need to check out Howell Engine Development for all of your LS wiring needs. The job never got any easier.
