if pretty low, how much low, i mean, computer cable can handle it or not.
yeah, once again, we not sure about the current to activate relay.

"The current draw by the coil of a bosch relay is ~0.160 amps (~75 ohm coil)."

That's a pretty small current draw... IMO, you're fine with a computer harness.
One other interesting thing to note in that article is to connect a quenching diode across the coil terminals of the relay to prevent back-EMF when you release the button. This will increase the life of the switch... I think I'm going to open mine up again and put one in.
