Tachometer Help

hahaha.. me neither 4spdragtop, but I'm trying to figure it out. I have two empty connectors, so I will give that a try first. Also, I learned from MoparLvr that the red/white wire goes to the radio and I can splice in to that if needed. I sent my dash off to Vae Restorations and I hope to get it back soon and put everything together...Thanks for all the help. It is appreciated....
