Roush installed a Pioneer D3 on a 02 sc281

[pbm.cc]

I just need to know if you guys know where I can get the vss wire hooked up to? I dont have this and the reverse wires connected. I understood that the speed sensor wire ii a white and orange wire but I took off the kick panel and there is like 3 or 4 wires of the same color? If anyone has done this can you give me some words of advise. Pictures would be perfection!

thanks in advance.
