    I purchased the Seasense trailer lights with wiring harness and the Seasense circuit tester on same order. The circuit tester does not fit the wiring harness by the same manufacturer. The tester did fit up with my old wiring harness, so I left the old wiring on the vehicle. The tester worked fine on the old wiring.
