[QUOTE="Alvin, post: 866494, member: 17890"] Abit interesting gadget, de idea is juz to self triggle de alarm siren make it sounds like whistling. A few tiny stuff dat I uses such as Push button switch, diode, wires etc, dats it. :biggrin: [COLOR=Blue]Step 1[/COLOR] Solder any side of the diode to [B]PB switch[/B](as shown on 1st pic) take note de direction of diode bcoz if wiring wrongly it wil not work, de purpose of diode is prevent miss direction of voltage or current(ignore de resistor coz de siren working in 12V, connect wif resistor wil reduce de volumn of siren). [COLOR=Blue]Step 2[/COLOR] : Trace de siren signal wire U can either trace all de way under yur bonnet cross de firewall, or juz trace from existing alarm console system. I manage 2 find my alarm wiring diagram n found de signal from alarm 2 siren, to double confirm it I simply connect one end of de wire to any 12V supply, another end to de siren signal wire n slowly "tap" de [B]switch[/B] to trigger de siren. [COLOR=Blue]Step 3[/COLOR] : Switches location Finally, get a suitable position 2 mount de [B]PBswitch[/B], dis is de best part, u hv 2 drill de hole slowly from small 2 bigger enuf for [B]PBswitch[/B], why must do it slowly? if not U may end up make a useless big big hole on yur dashboard, if U hv 1 set of drill bit, dat wil b easy 4de hard work. 2nd pic shows my [B]PBswitch[/B] located. Step 4 : No more steps to do :biggrin: juz tidy up all messy wiring n fix back everything. Done!! :wink: Now I can anytime use dis along de street whenever a fairy or angle spotted :biggrin: :biggrin: Happy DIY 2 all :smile: :biggrin: [/QUOTE]
