I have been working on a '69 400 for several months almost completely rewiring the front half of the car and the interior. I guess the guy who had the car before me was a butcher and not an electrician!!Any way there are no wires going to the relay which is a Delco Remy (may be original-not sure) but has no screw terminals on the side, only four blade terminals. When looking at them in mounted position it has two blade terminals almost making a T at the top, a single horizontal blade terminal in the middle and a single vertical blade terminal at the bottom. There is also no wiring at the horn itself. Can you point me in the right direction? Thanks for your help.
