I'm checking in on this post to see how you made out with this project. I was wondering what wiring your dad needed to reach, as there is sometimes a way without a full dash removal. If you did go through with it, I trust you disconnected the battery first to keep all the electronics safe.My dad working on some wirings on the driver's side and he said he needs to remove it to reach them. We haven't really tried this before so i'm trying to see if anyone can share instructions for us to try. thanks everyone!
