How do the wires on the 66 horn connect big red big black medium green and small black wire. The green and small black wire have plastic plugs. Any help?

Big Red..screws into the terminal marked 'Batt'
Big Black...lug goes on screw that attaches relay to rad support (ground)
Dark Green and small Black...to the terminals marked 1 and 2

But you are missing one, the Black with White stripe...goes to the same terminal as Big Red. You need this. It is for your Ammeter.

Corrected version of the wiring diagram shown below.

Yeah Buns Thanks
Sorry. The little wire was paired with the red on the lug. My relay has the two plastic connector plug-ins on the relaty marked 2 and 3 #2 is closest to the mounting bolt hole. Based on this does green go into 2 or 3? By the way great diagram.

Does your horn relay have the two spade connectors oriented as a "T" as shown in Buns' diagram? If so, the green wire (12V feed to the horns) goes on the top cross of the "T", and the black wire (ground from the horn button) goes on the vertical leg of the "T".

No they are not T'd. The unit is a delco remy, and the two spade connectors are in line with one another perpendicular to the mounting surface.

Put 12V on the screw terminal buss, ground on the attaching bracket; use a jumper wire from the ground side and touch it to each of the spade terminals - whichever one makes the relay "click" is where the black wire goes.

Thanks

I checked my horn relay , it is the same as hellamog's. Black wire goes to #2, Dark Green to #3. The #3 spade has a small tit (which is easily broken off) , and the connector has a groove to match it.

I also updated the wiring diagram above, for future referance.
