Hi, I recently signed up to this Korean Copen Club (since I'm Korean) couple of days ago. While I was going through the DIY thread, there was a "how to" demonstration on DIY open roof while driving. I saw few threads on Copenworld and I could see quite a few people were looking up on extra add-on units for ECU to get this thing to work. Took me a while to translate it since my Korean aren't that good. But here we go: Remove centre console. Once removed, cut out the wire wrap as shown with yellow circle. Once you have cut open the wrap; you'll see 3 wires. First arrow: speed sensor (light greeen colour; looks white to me) Second arrow: side brake sensor (thinner red wire out of the two) Third (no arrow): power Cut the side brake sensor wire (thin red wire) Once it's cut; extend the cut wire that is coming from the rear end;; connect to earth. (For this, you don't need to pull the side brakes up to open the roof) Lastly, cut the speed sensor. Now, you can open the roof while driving. (Do not speed over 30km/h when opening roof) I saw quite a few replies on this thread and it worked for all of them. Does anybody want to give it a go?
