Hey guys I just bought second hand an Evolution 45gt second hand and either it needs somthing else or i need help. The ICU has the wire that runs out to the crank and then it hase a 2 wire deal that runs out to the battery. My question is where does the switch to turn it off go?? I ask because the wire to the battery will not plug into any switch the i have seen!

you can ddownload an ignition manual from the Horizon site I believe.
If not, you can from my website, but I am not sure it is the same ignition as you have. (evolution vs MVVS)

PE i see the set up on your web site but i am missing the led wire and it i guess the other programming wire do i need those? and the instructions say to plug and unplug the battery can i not put a switch in between the battery and ICU?

Not all ignitions are programmable, so they do not need the programming cable. You need however the LED to check the ignition's status signals.
In the battery cable you can put a power switch. Any type that is vibration resistant and rated for about 5 amps or more.
I normally use a radio gear switch with charge bus, and if time permits I integrate a power-on check LED in it.
