Hey guys, I hope this is the right category to post in. I recently got a hold of some 19 inch wheels and want to be able to calibrate my Evo to reflect the change. I have a yellow box from my previous s2000 so I'm hoping it can be done. The question I have is where can I find the speed sensor wire? the wire the runs from the sensor in the ecu to the speedo? I need to tap into this wire to adjust according to the size of my tires.
