Wiring Part 1, Modifying RX-8 and Honda K Harnesses

     Hey guys, I finally got some time to start working on the wiring of this car. Me, having never done a motor swap before, had little knowledge of how you could wire in a motor from a completely different car. But now, after countless hours of research, I have the game plan figured out.      As I stated previously, I will be using a Hondata K-Pro alongside the stock Mazda ECU. This is the budget alternative to using the Adaptronics ECU , made specifically to interact with the RX-8s canbus system that drives the goodies, like the electronic steering, speedometer, ABS, just to name a few. If you're using a Hondata K-Pro, then this is what you'll want the stock ECU for.  Now, I also want to retain the factory RX-8 throttle body.

So that took my time and money for a good few months. The RX-8 project is no longer on the backburner, and will continue in full force :)       When I was putting the car together, I wanted to put some emphasis on how to get the clutch system to work, and also how to hook up the steering rack. Since the steering rack is lowered about 1-2 inches, the stock steering column is now too short to reach the rack. You need to use a Lexus IS250 Steering Column   U-Joint, part number 45206-30112. It looks like this picture below. We want to use this piece to extend from the steering rack , to connect to the stock RX-8 U-Joint  on the steering column. The part I have ci
