Group your TPS (Throttle Position), MAP (Manifold Pressure), and Coolant Temp sensors together.
Effective pinout design requires a deep understanding of signal types. Designers must separate high-current outputs (like injectors and ignition coils) from sensitive low-voltage inputs (like MAP or O2 sensors). Failure to do so introduces electromagnetic interference (EMI), which can lead to "noisy" data and engine misfires. Modern repacking often utilizes high-density connectors, such as those from Deutsch or Amphenol, which provide superior weather sealing and vibration resistance compared to aging OEM plastics.

Use a backshell or a boots-and-epoxy method to ensure that engine vibrations don't pull on the pins. The weight of the harness should be supported by the connector body, not the copper wires. 4. Testing the Repack Group your TPS (Throttle Position), MAP (Manifold Pressure),
