The Lingenfelter TRG-002 module allows Gen IV GM V8 engines with the 58x crankshaft trigger or reluctor wheel and the 4x camshaft timing gear to be installed in earlier vehicles designed to accept the 24x crankshaft trigger wheel and the 1x camshaft trigger wheel without having to take the engine apart to change the cam timing gear or the crankshaft reluctor wheel.
The Lingenfelter TRG-002 is a plug-and-play design that connects directly to your existing wiring harness and to the factory engine sensors and has its own power source harness. Some early Gen IV V8 engine equipped vehicles that will need a camshaft sensor extension harness.
