Hey all, quick question that may be dumb but I haven't done a lot of electrical work before.

I picked up these turn signals from American Sportbike for both the front and rear

Front went in just fine but the rear wires are no where near the length of the orig. wiring and I need to extend them. My question is, can I cut and splice using the factory turn signal wiring or should I get new wiring to extend the length. If you suggest new wiring, what gauge wire should I use?

Thanks
