Horn relay question 74 260

[Shawninvancouver]

when key is on i have power on steering wheel horn button and on green wire leaving horn on back of steering wheel..

under dash passengers side - at the plug that goes in to relay i have power  on two wires in the plug..  nothing changes when i hit the horn button.. is that correct prior to getting hooked up to relay??   or is something supposed to happen when i hit the button??? or is that only after relay is hooked up and working??

thanks
