Smoke in the Column????

Rewiring the 64 Dart with an Easy 21 circuit aftermarket wiring harness, had everything working using some of the old connectors to the new wires, gas gauge, temp gauge, dash light, turn signals, with the exception of the horn. After running the engine I noticed a puff of smoke coming from under the column itself!
Next attempt to run the car, now no gas gauge or water temp, but the turn signals were still working, again white smoke coming from inside the steering column!

Suggestions? I ordered a new turn signal wiring & was planing of removing the steering wheel and replacing the wiring, anything else in there I should be looking for?

White smoke, didn't have the usual electric smell and didn't smell like plastic melting either really didn't smell like anything!
