gauge circuit board

I've been troubleshooting my car (69 barracuda) since I put it back together after paint. The dash was out of the car when I purchased it so I've never had everything working before I tore it down. I have no brake lights or turn signal lights, but I believe that has to do with a faulty turn signal switch (I replaced it with a new one before paint..) Anyways I was going over the wiring diagram tracing wires, etc. I come to notice that the 2 prongs for the Instrument lamp and Left turn signal lamp are not there. I was able to take a picture with my phone as the dash is installed in the car. With these 2 pins missing would that only affect the dash light and the left turn signal indicator light? Would I be able to just solder new pins in those locations? (Obviously would have to pull the dash back out) If so does someone make the correct pins for those locations?
