I am completely rewiring my car and now am working on the dash harness. I tired to plug in the inginition switch plug and it will not go in all the way. So I pulled it out again same problem. So then I took the key tumble out no problem, but can't get the lock ring out. I was pulling it out so it would be easier to see where it is binding but no luck. Is there any trick to get the new inginition plug to go in all the way in ?
