Installing And Customizing Holley’s Dynamic Display

We’ve been making some serious progress on our boosted Silverado project. So far, we have replaced the factory rearend with a Moser Muscle Pak and ditched the 4L60E transmission for the robust TCI TH400. One of the more recent modifications involved removing the OEM computer and upgrading to Holley’s Terminator X Max.

While adding the new ECU certainly has its advantages, doing so can cause a dilemma with the gauges. Sure, there are patching methods and harnesses available to get the factory Silverado cluster to communicate with the Terminator X. However, it can get pretty involved, and you’ll need to purchase some additional components to make it work. So we hit the internet to see what our options were.

After looking at several gauges and displays, we decided to go with one of Holley’s digital screens. Our Terminator came with a 3.5-inch handheld screen, but we needed a replacement for the gauge cluster, capable of displaying the same information. Holley offers two screens, the 6.86-inch, and the massive 12.3-inch Pro Dash, which got us thinking: would the gigantic Pro Dash fit in the Silverado gauge bezel? Once again, we hit the web trying to figure out if anyone manufactures a housing for the Pro Dash.

Custom Solution

While several manufacturers offer solutions for the Pro Dash mounting, our Silverado was not on the list. Fortunately, we are members of a high-performance Silverado page on Facebook. So we asked if anyone was currently running the massive screen in a Silverado. The name that popped up was CarChains 3D.

This unique modular system allows you to change faceplate colors or use carbon fiber.

We reached out to Cory Nicholson, owner of CarChains 3D, and as it turns out, it offers a 3D printed solution for our project. We talked to Nicholson and figured out that not only did he have the part we needed, but the company offers several mounting solutions, including GM trucks, Mustangs, F-bodies, Corvettes, Trailblazers, and other vehicle makes…
