Will GM 200r4 work with factory floor shift location?

According to the 69 Service Manual the two outside wires that go to the tranny switch simply get connected when you put the car in reverse. The center wire (NSS) gets grounded to the tranny when you put the car in Park/Neutral. So I ran one wire from my new NSS (on the shifter) to bare ground. I ran two more white wires to connect to the two wires that connect the reverse light under the car. When I receive the reverse switch I ordered all I should have to do is hook it up the two white wires and install the switch with two screws and connect the other ends to the two outside wires on the tranny switch. I have a small grommet. I'll drill a small hole in the tunnel to pass the three wires through then I can reinstall the console and drive my car until I install the 2004R. This should resolve all the problems with the NSS and reverse light. PS - I'm seriously thinking about putting a by pass switch on the NSS circuit as a back up in case the switch ever goes out on me??
