Top of steering column of-set to the left, you can still see speedo needle
all your gear lights and tach, plus all warning lights, turn your ignition as far as you
can without starting car that way you can see all warning lights and position
accordingly...
Mount the solenoid near the factory one I guess easier with hoses etc..
*You might want to locate it to be a bit more stealth, just make sure all hoses
are on tight!
