Thanks for the kind words Mark!  I do offer a horn relay kit for stock horns
as well as an option for dual horns like the Hella Supertones that I run on
my van.  Here is a link to the single horn relay on my website:
https://sites.google.com/site/vanagonheadlightrelays/horn-relay  The dual
horn relay is $2.00 more and is set up with the same connections unless a
different type of terminal is specified that will work better for a specific
horn when ordering.  All of my horn relay kits include a weather resistant
sealed relay (since it will be exposed to the elements) as well as a small
packet of dielectric compound and mounting hardware.

If I still had the proper quality tools I would buy various new pins and
socket shells to build everything from scratch. Leave that to Jay Brown. He
should offer the horn relays as part of his Vanagon relay product lineup. I
like his work on those relay kits he sells. I stopped home making as many
"hard start" relays setups for people when he started offering them built to
a higher level and a very fair price. If he would just make single horn kit
and a dual horn kit.
