Just finished replacing my engine and forwad wiring harness on my 66 Malibu with some harnesses made by M&H electrical fabricators.

These harnesses are great, correct lenght, connectors, and wiring color. They are truely plug and play.

Unfortunately, I don't remember how to connect the horn relay. Other than the 10 guage wire that mounts under one of the two srews on the face of the relay, there are tow other connections that I heed some help with.

One connector has two green wires that merge to a single connector and the other is a single black wire to a single connector.

Can anyone tell me if the black single wire connecto plugs into the horn relay in thr receptacle lon the relay ocated closest to the radiator core support or does it go plug into the connector on the relay toward the engine block.

Thanks for the help.

Here's a picture if it will help.
