Starting circuit question BCM to ECM
I'm a little stumped after looking at the wiring diagram, trying to do an auto to manual swap on a 2007 vette.
Figured out most of it but this one thing is driving me nuts.
The ECM connect C1, according to the wiring diagram has a wire going from pin 19 to ignition voltage, while pin 4 on the ECM goes to the starting relay.
However on some diagrams it looks like only the Auto has pin 19 connected on the ECM to ignition voltage and the Manual has pin 4 hooked up instead.
While other diagrams it looks like the manual has both pin 19 and pin 4 connected, pin 19 to ignition voltage from the BCM, and pin 4 to starter relay.
Would anyone be able to do me a favour and see if your 2006+ Manual trans, ECM connector C1 (the black one) has a wire coming out of pin 19?
Thank you so much, cuz wiring diagrams show one thing in some while another thing in others.
