I'm wiring up some extra lights with a relay. I went to Fry's and bought the only 12V DC relay they had. Will this work?

Looks fine.

Here's how you hook it up.

What Tipsy said

Will work fine

Just make ceratin that the connectors you use are soldered as opposed to crimped, and sealed with heat shrink before you connect them to the relay and all will be well.

Good Luck

There should have been a connection diagram on the box or on the relay itself. I wouldn't just use a generic diagram on the web.

I have fought many a wiring problem on Milwaukee vibrators and here's a trick I learned that works well. You can solder or crimp your connectors. If you crimp then put some dielectric grease on the wire before you install the connector. Always use shrink wrap but don't shrink all of it. I leave a 1/2" extra on the shrink wrap. I heat the part that is over the connector but leave that last half inch unschrunk.? If you shrink the whole thing then the wire will bend back and forth at the end of the wrap and possibly break down the road. If you leave it unshrunk it will bend a little taking the stress off the wire. I found this out on a wire going to the horn on an electra glide. I tried many different ideas but the wire got so short I had one last shot before making a new wire and this is the procedure I used and it's still going 50,000 miles later.

Here's the diagram Tipsy linked for posterity:





Mine had a diagram on the side, but the meanings of symbols weren't obvious to me. The spades were numbered the same as the diagram, though, with the exception that mine has both 87 and 87a. One's energized when the relay is activated, and the other is energized when it's not.

I wired it all up, and it works like a charm. My aux lights come on with my high beam. Now I just have to put everything back together. I'll post some pics tomorrow.

It seems that ever time that any wiring thread on any bike forum comes up, someone will post a warning to only solder connections and never use crimped connections. Well the whole OEM wiring harness is made with crimped connections! If any one sincerely believes that crimped connections are bad they had better start rewiring the whole bike.

There is nothing wrong with a properly made crimped connection. The key is to use a proper crimping tool and not the crimp notch on a dollar store wire stripping tool. this is what I use http://www.mytoolstore.com/klein/1005.html
