On this page, we cover the typical installation configurations for an electronic boost control solenoid. There are other ways and other solenoids, but we're going to focus specifically on what we've actually tested to work. This includes the Ingersoll-Rand 3-port solenoid and the factory boost control solenoid.

The first thing you'll need to do is to wire the sensor into your harness.

To do that, locate the factory BCS connector under your hood. It will be located near the passenger side headlight area and will look like the connector to the right.

If you are installing a stock boost control solenoid, then this step is pretty easy…just plug the solenoid into the stock harness.

If you are installing an aftermarket solenoid, then you'll need cut the factory connector off the harness and hardwire (solder and heatshrink) your solenoid into place. Wire color and which wire goes where doesn't matter here. One side is +12v, the other is a switch to ground from the ECU. It doesn't matter which goes where on the replacement solenoid.

Alternatively, you can wire up a pigtail if you'd like.

Because we have to test several different solenoids and have to maintain the ability to test other solenoids in the future, we have a small pigtail made up using a connector from (I believe) 2G fog light wiring.

A picture of this connector is to the right. That plugs directly into factory boost control solenoid connector shown above.

On the other end of this pigtail, we have a generic connector that we then use for all our other solenoid pigtails so we can swap different solenoids in and out at any time.

If you are installing this on a turbo with an internal wastegate and you have 3-port solenoid, you'll want
