Description

An LS engine swap is a no-brainer when it comes to adding some affordable horsepower to a project car. Unfortunately, any swap comes with its share of headaches, including wiring—and that's where Top Street Performance standalone fuel injection wiring harnesses come in. TSP offers three harnesses for drive-by-wire/drive-by-cable applications and they include a fuse block and all the connectors for a headache-free install. Order the harness recommended for your system.
