Yes I am having trouble... My horn does not work in my 1999 Toyota Corolla and I looked and I have the norn but do not have any wire connecting with the horn... So will I need I new wire and if so what would it need to be connected to besides the horn?

If the original horn wire has one wire, then the chassis is the ground. So just connect a wire from new horn to any metal part of chassis. Here is a guide to help check for power with the horn wiring diagrams below.
