I would say that your first two wires are for the units power and ground . The other 3 are most likely domelight wires. The purple is probably the door trigger wire. How you connect those depends on the vehicle. (unless you just want them to be "map"lights. to do this, just simply tie your domelight power wire into your unit power wire and your domelight ground into your units ground wire. That way you dont even have to mess with the purple one, just tape it up or put a cap on it

you're correct the other three are domelight wires. How you hook them up depends on whether your vehicle has a negative or positive switched domelight. If it's a positive switched then your hookup will go red to constant 12V+; BLACK/ red to ground; purple to switched 12V+.

Toyotas generally have a negative switched domelight configuration, so your domelight common will go to 12V, the auto wire to your switched ground and the constant wire to a chassis ground. There should be 3 wires in the harness plugged into the back of any dome light in the car; you just need to test them and see which wires are which.
