Rewiring no longer has to be a headache-inducing process thanks to Painless Performance. Whether you’re working on an LS
engine swap or converting to electronic fuel injection, Painless EFI wiring harnesses make the switch easier. They can
also replace any corroded or broken wiring.
All Painless EFI wiring harnesses include:
TXL high-grade wiring
Factory style computer connectors
Dedicated fuse box and fuel pump relay
OBD II plug and check engine light
Painless tests every EFI wiring harness to make sure all the wires are pinned correctly. Each wire comes labeled, so
there’s no guessing what wire goes where. The harnesses come with everything needed to complete the installation. Along
with EFI wiring components, Painless also offers complete chassis wiring harnesses.
