ok so i went to an autoparts store and bought a wireless module to be able to turn shit on wireless.my goal was to be able to blast my train horns.this is wat i did .from the module it has a pos and neg wire which is for the power.then is has the 4 other channels.so i connected the pos and neg for power,no problem.i chose the 1st channel,it has two wires one for pos and one for neg.i connected the pos to the pos of the horn which goes to my push button for the horn and the neg to grnd.i hit the button and i here it clickin but no blast.im really confused why it doesnt wrk.my friend told me sumthin bout a relay but he didnt know how to explain it,lol.
