Troy did you have much trouble wiring up the hazard switch? I have the watsons kit as well and have one wire from the fuse panel for a hazard switch but no idea how to wire it up (I am using a hazard switch off early 70s beetle - it has a bout 8 spade terminals on it and I have no idea what they are all for!).
Also any trouble wiring your horn up? I know one wire goes to horn (for +ve power) and in the original set up the ground wire from horn was connected to the steering column (63 beetle)....and another wire from horn button to steering coupler. However in the watsons kit there is the green wire for horn +ve but also a black HORN SW wire for horn switch - but I don't know where this one should go!!
Sorry to hijack your thread! How does the audio system sound??
