Hallman Manual Boost Controllers are typically adjusted right at the controller with a simple turn knob. With the addition of this add-on kit you will be able to control boost levels right from the driver's seat. You'll no longer have to go through the tedious process of stopping and popping the hood just to adjust your boost settings! Please note that this kit only works with the Hallman Pro and Hallman Pro RX manual boost controllers (MBC's), it will not work with the Hallman ES boost controller. This kit includes a 72" cable that needs to be routed from your Hallman MBC to the desired location in your cockpit. Once routed and functional just secure it in place with some zip ties and you're ready to go.
