Home > Gen IV LS / Vortec Harnesses > Speartech Standalone Harnesses
If you all ready have an ECM, TCM, and throttle pedal for your swap project, or prefer to find the parts on your own, then we offer our Speartech standalone harnesses by themselves.

We have been in the business for over 20 years perfecting the process of LSx harness building to ensure an accurate fit, quality appearance, and trouble-free operation. All harnesses are built in house, on an actual engine and test ran with a GM Tech 2 diagnostic scan tool hooked up to ensure proper functionality before shipping.
