I read every post and I'm still confused. I allready have my alky kit installed with 3 bar sensor with the pp pigtail. I have the Powerlogger installed in the ECM. I would like to record boost. I understand I need 5V reference/power and ground to accomplish this? I read on buick vortex the digital cars did not have the necessary wires behind the glove box to get required 5V reference/power to read boost. Please advise.
