Classic Instruments pull-up resistors are needed to enable their standard (non-ZST) tachometers work with your GM LS-Series engine. The pull-up resistor will boost the weak LS 4-cylinder signal to the tachometer to one it can recognize. Most stock ECM GM computers will require this part to function correctly with a standard tachometer.
