Need a little wiring insight I'm on the final bits of the wiring and had some questions regarding it.
It's an 03 DWB 5.3 from a Tahoe and swapped to a 4L80E.
C1 Connector (Blue)
Pin 58 - Serial Data Connection - This goes to OBD2 Port, correct?
Pin 39 Start Enable - Does this go to the ignition switch or the starter relay
C2 Connector (Green)
Pin 10 - Engine speed - Tachometer signal wire?
Pin 50 - VSS - Speedometer signal wire?
Pin 46 - Check engine light wire?
Pin 9 - Starter Relay - Same as Pin 39 on C1, Does this go to ignition switch or relay? I"m thinking this one is to the relay and the one on C1 goes to the ignition switch.
Pin 55 - Crank Voltage - Just hook this up to the 12v ON and RUN power source?
Also, there is a blue wire from the alternator harness, not sure where it went. Came from the C100 connector
And just to verify, all pink wires are key ON and Start 12v and orange wires are 12v all the time.
