I have a Greddy Turbo Timer without a harness or a wiring diagram :( ..the colors coming out of the turbo timer are Red, Green, Blue, Black, Brown, Purple, and Grey....I know that constant is Red, and Black is ground, but thats about it..does anyone know where the rest of the wires are supposed to go?

If not, what can I do to get this installed??

Thanks,
Zoeb

i had the same problem. and greddy does not make a harness so just by a HKS harness for a skyline R32 ,33, 34. they are all the same. fit perfect. 15 buck for the harness
