LS & LT swap wiring
Standalone harnesses
Electrical diagnosis

Detailed engine bay wiring work at Foulks Performance — Clean swap wiring is the difference between a build that feels finished and one that keeps coming back with mystery issues.

Electrical cleanup

Wiring work for builds that are supposed to stay sorted.

Harness cleanup and swap integration are where patience pays off. Foulks Performance is the shop customers call when they are tired of butt connectors, bad grounds, and "it should work" electrical guesses that never really hold up.

Swap Integration LS, LT, and other swap projects wired so the engine, ECU, and supporting systems cooperate.

Cleanup Work Messy harnesses and prior bad installs get reworked into something serviceable and reliable.

Diagnostics Intermittent no-starts, charging faults, and sensor problems are traced instead of guessed at.

Who it's for

Swap builders and drivers with electrical problems nobody else can figure out.

Foulks Performance handles this work with patience and proper diagnosis instead of shortcuts that leave the problem for next time.
