Swap Specialties and Performance
Your Source for Standalone
Swap Specialties and Performance standalone wiring harnesses for GM, Mopar, and Ford have proven to be the best wiring harnesses on the market today. We hand build every harness to fit exactly what your project needs. We use the highest quality TXL wire, brand new OEM connectors, weatherproof fuse and relay box, and finish it off with a multitude of covering options. Each harness is then tested on an actual engine dyno and double pinned to assure it is 100% thoroughly checked. That is why we are “Your Source for Standalone!”
Swap Specialties offers Standalone Harnesses, computers, and performance setup & tuning for: GM LS, Gen5 LT, EcoTec, Duramax, 3800, Coyote, and HEMI.
