    Looking to upgrade my 8foot HD straight to a 8.6 V..... Will I need to change everything on my truck?

    I may be wrong but, the push plates, headlight harness, and module are the only items you can reuse.

    100% correct. Only thing your going to reuse is the push plates, headlight adapter harness's, and the Iso mod itself. Everything else needs changed.

    Is it the extreme v? If it is you need a new iso because they are only two wire. The ezvs are 3 wire.

    Push plate will definetly work tho so don't worry about them.
