Did the service manual screw up?.......
I am moving some wires around and double-checking others.
I came across something that confused me with the D21 circuit from the ECM to the Data Link Connector.
The description for the ECM C2 shows pin 16 "SCI Transmit" on the pin-out chart but when verifying the wiring path in diagram 8W-18-3, it shows D21 depicted as "SCI Receive".
Can someone tell me which is which because I don't want to fry the ECM.
