Brand new TPS adjusting harness for TPI applications. Mounts between the engine harness and throttle position sensor (TPS), and allows you to adjust the sensor voltage with a voltmeter. Can also be used to troubleshoot a potential TPS problem. These are assembled in house with new connectors, terminals, and seals from Packard, and TXL grade wiring. These are the same products used by GM on factory harnesses. We use the same colors as GM did on factory harnesses.
