front signal wires

How many wires does each of the front turn signal supposed to have. one of mine has 1 wire, the other is a 2 wire. Cant seem to get this wiring thing going well. Im starting to believe that the previous owner did not put the proper signal(s) required for the front. The front one and back ones are indeed different right?

Ay help appreciated.

Thx

 

Front and back should be the same if they are stock.

Some lights have two wires, some have 3 (if they double as running lights, not on all models)

My fronts have a single wire coming from the stem, then I had to add the ground wire by crimping a ring connector on a piece of wire and running that wire from headlight bucket (bullet end) to the signal stalk (ring end)

They aren't going to work with just one wire though, they gotta be grounded.
