I'm rewiring my 49 pickup with the CD aftermarket harness. I have three wires to connect to the two terminals on the switch. I have the hot lead to the switch (ok) and the lead from the switch to the stoplights (also ok) but I have a third wire that goes to the turnsignal switch.

I assume this is for the flashers and should be spliced into the wire going to the stoplights.

Is that correct?
