3800 Standalone Harness for NA and Supercharged

Base Price: $399.00

Got a buggy? How about a 3800? If not, get one! Everybody knows the 3800 for its durability, power, and reliability in the GM cars. It goes even better in a buggy, rail, or 4×4. We custom make each harness and engine run it on an engine before it ships. 3 wires (that are provided) and your running. Our weatherproof fuse and relay box that is built onto the harness can be mounted anywhere. Ask about our VW trans adapter plates to make your swap that much easier and faster. Let us know if you have any fitment questions or if we can customize a setup for your project.
