Quick question, I am working on wiring up a harness to use with a GMPP E67 controller. I've found that on a 1st Gen CTS-V, Alldata lists pin 14 as the fuel pump relay trigger. TBSS, and Corvette LS9 pinouts list pin 13. I'm guessing one of these is incorrect, I'm just not sure which one. Can someone with a GMPP harness take a look at pin 13 and 14 on the blue connector, and let me know which is not used?

Thanks!

Download the GMPP harness instructions. They have a pinout.

Ah, got it. Thanks. Looks like it's pin 13.
