Quick I need help!

I'm trying to install my turbo timer but I ran into a problem. I have two red two blue and two black wires! Which is which? I need to know which ones are 12v, Acc, and On. Please help! I feel really stupid right now

Verify all wires with an airbag freindly test light or preferably a Digital Volt Meter like the Fluke 23. Be sure that you have true ignition, true accesory and true 12v constant before wiring anything.
