Yup, wiring issue alright. I reinstalled my Procede last night just before trip to the beach with wife and kid. In my haste, I didn't do a good job securing the wires and got the 335 code. After rechecking and rewrapping the connections the code went away.
I also forgot to ground the procede before testing forgetting that I don't have the bypass plugs... Ooops, instant limp mode, and check engine. Eventually I was able to clear all the codes somehow, took a few tries with the C-Reader and patiently waiting for car to power off and on...
Needless to say I didn't finish the install in "under 15 minutes" as I promised my wife...
