This is a UNIVERSAL harness, which uses top quality, fire resistant crosslink wire. Each wire is printed so there is no confusion as to where it is going. This comes with turn signal wires if you choose to use them. We also offer a nice clamp-on turn signal switch (shown below) which has a 4-way flasher switch and indicators built in. We also have an assortment of other switches which can be used with 6 volt systems.
