Now...... although not being in the DIY section ( which should be and I will write it if I have some extra time as I have the MSP in my garage still but "thewrench" already has done it forward and backwards......)
You did come in here a bit strong M2P503 expecting help and basically insulting members as no one posted. It's a simple procedure involving a multi meter to check for voltage. Get a test light as well. Very helpful tools that will get you through a lot.
I am confused though as you helped someone else to do this conversion in April and stated you did this to yours but you are posting afterwards that you need help? Just click on wallabe's link which ends in "PDF". That explains both to and from.
Your posts.....

What I get from this is you understood it and knew what to do. My question is what is confusing about it? If you are confused about wiring or how to wire it my suggestions to you are buy male and female h4 adapters for each side and convert inbetween so you don't cut any stock wires off your harness and follow the PDF. Thats what I would do......

This is the reason why you need the relay and why the P5 and Sedan are different:
Some more interesting reading which I have to concur with "The Man". I have owned the sedan and now the P5. My sedan lit up the road better as well but to each their own. I prefer the P5 Headlights though because of the sidemarker delete and ease to retrofit when in a P5 using P5 stock wiring.
