I want to replace a left turn signal on my wifes 2007 honda vlx 600. The plastic chrome is cracked. I have not done this before. How are the wires reconnected. (Have not taken it apart yet or bought the parts) Are they plug in, do they need to be soldered. wire nut or what. I dont want to take it apart and then have to take it somewhere or wait for another part to be delivered to the dealer. Do I need to pulled the headlight.
