notes:

gamit ko ay Bosch Relay 5 pins/terminals (2 x 87) pn: 0 332 019150
sundan nyo lang yung pin number - all new wiring connections na yan..
pinutol ko na yung dati sa oem wiring for busina.. itinaira ko na lang ay
yung wire sa stalk or loob ng manibela papuntang contact ng horn..

better use different pair of horns w/ different Hz and different or same DB para pansin yung tunog..
EX:
pair 1 (350Hz low 420Hz high 114 DB) bassy ang tunog.. and pair 2 (500Hz low 600Hz high 110 DB) matining naman..
yung mas mataas na DB yung mas malakas ng kaunti..
yung mas mababang DB (pair 2) na matining yun ang gamit ko sa Push Button Switch.. sa Single..
kasama rin siya sa Dual.. kasabay nya sa pagtunog yung pair 1 (350Hz low 420Hz high 114 DB)..

Thanx sa mga Tsikoteers and TPC guys na tumulong..

Paps 85 at 86 ba yung stock wiring ng single horn pag ililipat sa relay para makapagkabit ng dual horn?

paps di ko gets eh.. basta pinutol ko yung wire ng busina sa loob ng steering wheel module..
yung papunta sa contact or ground wiring ng steering wheel horn button.. then new wires and
relays and fuses na.. near sa battery yung relays and fuses.. from pin 85 yung papunta sa Single
push button contact/ground at pin 85 din yung papunta sa Single or Dual steering wheel button..
gumawa kasi me ng DIY fuse and relay box para foglights and headlights ko eh.. sinabay ko na Horns..
DIY upgrade lakasan ng loob wiring heheh..

Nice DIY, medyo maparaan telephone protector ang ginawang enclosure..haha

Comment ko lang medyo delikado yung cutting of wires. You could have made a safer route by tapping on the existing (no cutting involved), then additional 1 relay, 1 NO switch,1 fuse then optional selector switch lang ang kelangan ilagay.

puro mas mataba kesa sa OEM kasi paps yung mga bagong wires ko eh kaya
hindi ko na ginamit yung linya ng OEM busina at tsaka para bago na lahat wires...

Simplest way is to tap from the existing ground-signal of steering horn-switch, the rest are wired separately.

You will just need a handful components - 1 relay, 1 diode, 1 horn switch, 1 fuse, your addtnl horn, and an optional disconnect switch.

may na-tackle din kaming ganyan with DIODE pero pinili ko yung seperator/switcher relay
para sakto sa gawa kong box heheh.. parang ganyan yung ckt nya nga.. mas less components..
