so i fried my stock DI box (red) in my '97 900 and i replaced it with one that was handy. The one I replaced it with was black and it's aparently used on the Trionic 7 models, not the t5's. I've heard numerous things and Im not sure what is correct. I heard it was fine, I also heard that you can replace the red t5's with the black t7's but you can not replace the black ones with the red.anywas does anyone know any usefull info?
