I did this wiring changeover 10 plus years ago, I will try to remember the highlights. You will have to remove the White??? wire from the turn signal connector at the bottom of the steering column, this disconnectes the brake light. You then use the third brake light wire as your source of power for the brake lights. This will allow you to split the single bulb system to a two bulb system. We live an hour away from each other, and I get up to you area a couple times a month. Let me know if I can help. This change over was in one of the Corvette magazines in the early 90's, can't remember which one, maybe you can Google it?? Bob

I know I have a rear tail light harness sitting in a box in the barn.

I didn't want to cut up the original harness so I used scotch locks to wire the extra sockets to the euro lights. The wire you disconect is at the harness connector for the turn signel switch at the base of the steering collume [white??]. I taped into the third brake light wire to power the brake lights. If you don't split the two systems there is a feed back problem. I did this back in 1997, I still have the car if you want to look at it. PM me for a phone #.
