Magnum wiring help

There are many threads here with same question. If you go down about 15 threads there is one titled "wiring" that listed the main component wiring you need to keep. www.forabodiesonly.com/mopar/threads/wiring.397283/

It does not matter if you have an OBD1 or OBD2 donor system, you still need to keep the same sensors and outputs. Buy a Chiltons or Haynes manual so you can identify correct wire positions and colors in connectors. You need power and ground for your controller, and everything needed for your application, and I would recommend wiring in a data link connector so if anything goes wrong you can read codes and data. Also, a Magnum engine Powertrain Control Module with one big connector is OBD1 and three smaller connectors is OBD2.
