Hi
Need some help please. I tried to install the AEV Pro Cal snap to program tires size and plugged one end of the wire harness in behind glove box into the green star connector, then the other end of the wire harness behind OBDII then plugged the module into the OBDII face plate and tried to marry it and would not, just kept flashing red. So I unplugged the module and the truck and tried to drive it and the check engine light came on and then the dashboard when haywire. So I unplugged the wire harness from the back of the OBII and tried to unplug the harness from the green star connector but it wont budge.
Any advice? Should I try to reboot the whole system? Not sure how to reboot the whole system or unplug the harness from the green star connector.
Please help if you can. Thanks
