I hope someone can help. I need to know the pin #'s on the blue ECM connector on a 2010 ZR1. I'm needing to pin a new wire in the blue connector and when I opened the connector there were no numbers or labeling. I did a few google searches to no avail.

Top connector of the three is the "blue' connector. Pictured before I detached it and took it apart to pin the wire, only to find they are not numbered. I need to locate the #5 pin.

Thanks Joe!

When I clipped the zip tie that holds the wires as they enter the connector, it exposed that edge of the top of the connector... which had the pin numbers at the end of each row! @ myself.

LOL, The numbers are usually on most of the connectors somewhere, but can be really small and hard to read. At least you have the pin out with all the wires now.

It was nice talking to you yesterday & good luck with your project.

Finished up last night. Just need to reload my tune, as I sent it to DSteck and he modified it for me to turn on the flex fuel features. Then it's off to tank up with E85 and do some data logging as a precaution before I put my foot fully in it.

My finger is pointing to the new wire I had to pin and then a shot of the connector back together ready to go back on the ECM.
