i also would never re-pin the vehicle-side harnesses. GET ADAPTER HARNESSES AND HACK THEM UP.

re-pinning oem harnesses works great until you need to troubleshoot it after forgetting what you did all those years ago--how do you think i know this one?

add-on adapter harnesses are less than $50. just get the harness.
