I've searched and still can't find an answer to my question. Does pin 59 on the Green connector from an '03 Silverado need to be brought to 12V when the engine is being cranked? or does it provide power when the engine is cranking?

Thanks in advance.

Should be hot (12v) when cranking.

Thanks, so just to clarify, I need to provide 12V to this pin from the ignition switch when cranking right?

I think crank volt runs from the start position on your ignition switch to the PCM, providing it with positive current, not a ground. This will tell your PCM to hit the starter relay and engage the starter, as long as your clutch is pushed in (MT) or your vehicle is in park or neutral (AT).

So if I'm using the starter solenoid wire coming from the stock harness of the Jeep I'm swapping this into to start the engine, do I still need to provide a signal to this pin to let the computer know I'm starting the motor?

Green 59 is going to need a constant 12volts while the engine is cranking. You're going to need a test light to search the Jeeps stock harness to find a 12volt source that has constant 12volts running thru it while the key is being turned. Put the test light thru the wires and start turning the key. If the test light blinks while the key is being turned then you dont have the correct 12 volt source. The test light should be off while ign is in off position and it should stay lit while the ign key is being turned.

Thanks, so can I just use the same 12V line I use to trigger the starter solenoid and run a wire from it to pin 59?
