If you are the owner of a Chevy 350 equipped with a High Energy Ignition (HEI) system, you know what it means to have reliable power and performance. But with that power comes some wiring headaches. Fortunately, wiring your Chevy 350 HEI doesn’t have to be a chore. With a few simple steps, you can get your engine running with maximum efficiency in no time.
The HEI system was introduced by GM in 1974 and used until 1994, giving Chevy 350 owners a powerful and reliable way to fire up their engines. But the wiring that connects the parts of the system together can be confusing, especially if you’re not familiar with electrical systems. To help make things easier, we’ll walk you through the process of wiring your Chevy 350 HEI so you can get back on the road quickly.
Your first step is to locate the HEI distributor on your engine. This is where the spark plugs connect and where the power for the ignition system originates. Once you’ve located it, you’ll need to attach a wire from the ‘BAT’ terminal on the back of the distributor to the ‘BATT’ terminal on your starter solenoid. This will provide power to the distributor when you turn the key.
Next, attach a wire from the ‘IGN’ terminal on the distributor to the ‘IGN’ terminal on your starter solenoid. This will provide power to the distributor when you turn on the ignition. You now need to attach a wire from the ‘TACH’ terminal on the distributor to the ‘TACH’ terminal on the dash. This will provide a connection for the tachometer to read engine speed.
Finally, you’ll need to connect a wire from the ‘COIL’ terminal on the distributor to the ‘COIL’ terminal on the starter solenoid. This will provide a connection for the ignition coil to receive spark. You’re now ready to fire up your engine.
Wiring your Chevy 350 with the HEI system doesn’t have to be a headache. With a few simple steps, you can get your engine running with maximum efficiency in no time. So don’t let complicated wiring keep you from enjoying the power of your Chevy 350. Follow these steps and you’ll be up and running in no time.
