Do you know what brand and model the signal switch is? Try doing a web search for the wiring diagram.

I went through this same task on my 1948 Chevrolet.  Every signal manufacturer uses a different wire color code scheme.  Below is what I found online for SignalStat900.  You will have to figure out what make and model you have and search online for correct wire diagram.

If you have a multimeter, you can figure out the circuit.  Not too hard to find the flasher to front lamp wires.  The rear is a bit more difficult if you have the brake circuit going through it. There will be a common wire to the 2 rear lamps when the lever is in neutral. This the brake lamp circuit. The lever has to disconnect the brake circuit, and connect the signal circuit when moved right or left. Oregon Desert's diagram should be helpful.
