You would have to follow the wire from your ignition going to the Neutral Safety Switch, cut it, cut the wire leaving the Neutral Safety Switch going to the starter solenoid, and tie them together, thus bypassing the switch.
Not really that hard if you can locate it.
It's basic function is to prevent the ignition switch from actuating the starter solenoid unless the transmission is in park or neutral, therefor tying the wire from the ignition switch to the wire for the starter solenoid effectively removes the switch from the circuit.
Maybe someone else can help you with wire colors...
...It shouldn't be too hard, the Neutral Safety switch is located on the driver's side of the transmission, there are 4 wires going to it (one ignition, one stater, "I'm guessing" one reverse lights positive, one ... some other purpose... dunno...), just measure which one gives +12V when the ignition is turned to start (2 people is great for this!) that is the ignition wire, and which wire goes to the starter (I would just tap each of them with a +12V wire until the starter actuated, not necessarily safe... but it will work, just make sure it's in park... lol), the only other thing the switch controls is reverse lights. I would cut the wires high so if you wanted to reconnect them later you still could and leave the plug in so the reverse lights and whatever else still have a chance of working...
BTW: You can buy new Safety Switches for around $50, just so you know whether it's worth it too you or not.
