If you have a Bentley for any 1985+ VW car you can find the wiring
diagram that shows the wiring for dual horns and with the same relay
panel as 86+ Vanagon. Jetta, Quantum, or Cabriolet, any of those
Bentleys that cover 1985+ will have it.

I would put a relay closer to the horns myself since matching the stock
dual horn relay wiring is more a complex process than it needs to be,
among other reasons.
