Pro-Series Harnesses

Designed to meet the demands of the most professional builder!

If you have been using our 21 or 28 Circuit Customizable chassis harnesses over the years, it’s time you check out the ALL NEW Pro-Series!  The Pro-Series allows for customization of the harness by providing ample length wiring, giving you the freedom to route and cut the harness to fit your exact setup.  With over 25 GM connectors, you can turn your custom routed wiring into a Direct Fit for your build!  Just a few of the other upgrades include a 6 gauge charge wire for modern high amperage alternators, LED Smart Fuses, ground straps, light sockets, heat shrink, and much MORE!

Bulkhead Or Grommet Pass Through

Bulkhead – The bulkhead option utilizes the GM Bulkhead firewall pass-through used in most GM vehicles from 1968 and up.  The GM A-Bodies, F-Bodies, X-Bodies, etc. all used this bulkhead.  Those with other vehicles wanting to utilize the bulkhead can trim their firewall to fit the GM bulkhead using the provided to-scale template in the manual.

Grommet – The grommet application allows you to route your under hood and headlight section wiring through a provided grommet, allowing freedom to pass through the firewall where you choose.  Those running a completely smoothed firewall will likely prefer the grommet Pro-Series.

Pickup – The pickup option utilizes the same GM Bulkhead as the regular bulkhead application, but the tail section wires pass through the bulkhead, allowing them to be routed along the frame like factory setups.  The bulkhead is a direct fit for ‘73+ GM trucks, and the firewall can be trimmed on earlier C10s or other brands and applications using the provided to-scale template in the manual.
