How many are running factory efi on your magnum swap?

Don't use this post as a detailed list because I am going by memory, but it's a start.
Inputs include TPS, MAP, IAT, O2, ECT, camshaft sync (distributor), and crankshaft sensor.
Outputs include fuel injectors and IAC.
You also need correct battery and ignition power feeds and ground feeds for the PCM.
This would get it running. Other circuits are optional, such as air conditioning connections. It would also be good to include a data link connector for future diagnosis or programming, so keep those wires too. Always use the correct wiring diagrams to identify all these wires properly and note that most Magnum engines with OBD2 can be wired the same way, but wire colors change from vehicle to vehicle and year to year. A Durango TPS wire could be a different color than a Ram pickup TPS wire, even the connectors are the same.
