Having same issue. I am positive the wiring is correct b/c I checked the wiring 3-4 times during install. I connected them all, after connecting I went back through the instructions to check connections over and over. I then wrapped them in electrical tape for now. I am waiting for everything to work successfully then I will solder them.
I connected cable to laptop and afc, computer found driver and installed successfully. I did not do goto device manager and check com ports b/c the only one that would actually have the 10 second timer appear was com 3 and then the error came up. I turned the car on but did not start engine. The cable I have came with the AFC as the previous owner used on his.
Below Ken mentioned that if the unit is installed the car will not start if it's a defect correct?
Any suggestions before i go back out and try? I may make a visit to my buddy Sean's to see if his cable will work.
