Hi all. Plan: install switch to allow use of stock or added (2) louder horns via 2 relays. Stock horn switch (ground) --> SPDT *switch to control negative to 85 of either new relay. Don't know if using an 87/87a relay would reduce amount of wiring but here's a quick diagram using 4 pin relays: http://tinyurl.com/3k2lwx4 *switch would be labelled "Angry" and "Happy" just to confuse the next guy. ;) Is there any reason why I shouldn't take power from B+ to supply power to new horns? i.e. I could sound the horn, key not in ignition. Neil.
