Just another Update after this long time, Been some nice weather so I was able to work under the hood today.

Finally got my Reverse lights and trunk release working today!

The Orange wire coming from the Park Neutral Position Switch was corroded so I had to cut a 2 inch section out and replace it with a new wire. Soldered it up, put everything back and they both work now

So looks like I have 3/4 main problems working perfectly, just have to get the cruse control working, haven’t tried any of the suggestion yet, been worried about the main problems first, will have to try it another day.

So thanks for all the help so far!
