Hmm... site sponsor... Nelson Perormance can build you a harness for your application (so I'm told). ALLEN!!! Insight needed here!

-OR-

Check out ALLDATA for schematics on both year models you're looking to mesh technology into one (If you don't have a Haynes/Chiltons manual). Take your time, and dot all "I's" & "T's". This is VERY tedious, and will consume a LOT of time. Be thorough! Been there, done this. If I decide to do over, Allen will be the first to know.

Anyone else have anything to add?
