Heeeelp guys

I did some cleaning on the engine bay and i disconect some wires.
Where do i have to plug the green wire???and then te black
see the picture below its the horn relay next to the junction block

green wire on the left or right ?



Thanks

 

Note that one terminal has a small tab on it and one does not. One of the female terminals will have a slot in the plastic connector body to fit over that tab, the other will not. GM tried to design these cars to minimize the chances of improper connection on the assembly line.

 

ok thanks Joe

I'll try tomorrow morning

 

well, the plugs seem to be the same ????
so, where do the black one goes ???
thanks for your help

 

Well, that's your problem. They are supposed to be installed in a plastic connector body that has the notch that fits over the tab. The foolproof way to verify the terminals is to use a voltmeter. One of the terminals will show 12V, the other zero. The black wire goes on the terminal with 12 volts. If you don't have a voltmeter handy, connect the black wire (only) to one of the terminals. Press the horn button. If you hear the relay click, that's the correct terminal. If not, connect it to the other one. Once you have the black wire on the correct terminal, the green wire goes on the other one.

 

By the way, this is what the plastic connector would look like.
