Driving lights wired with Murph’s relay kit

TGIF from Minneapolis…

I am reinstalling LED aux lighting on my ‘99 Concours. Previous owner had installed with a relay and switch that’s not tied into the headlight hi/lo switch. Powered directly from the battery. The old relay died and I just bought a relay kit from Murph. Electrical is not my strong suit so requesting guidance on how to wire in the relay. My first attempt had my aux switch powering the headlight on/off (with ignition off) but no aux lights. I can’t find a wiring diagram or discussion specific to which terminals on the relay go to which wires for the aux lights and aux switch. Thanks for directing me to the light of day and night. 1752839636952.png

As I recall;
You should be switching the relay with the 3 wires (from the headlight switch). I think that you use the wires that are at the original headlight plug.
Neg/Low Beam/High beam.
This assures that the headlight cannot be left on when the bike is not running.
Aux lights are switched on by low beam selection.
Aux switch can be added to the aux wiring.

Someone can should check me on my memory about this.

Ride safe, Ted
 
How do you want the aux lights to operate? Do you want them to come on only with headlight low beam, headlight high beam, or controlled manually with a separate switch?

How are you powering the relay? Do you have an aux fuse block? If this is the only accessory wiring, you could feed it from the 10-amp acc circuit on the bike (provided your lights draw less than 10amp), or directly from the battery with an inline fuse.

There's a handy wiring diagram posted here:

C10 wiring diagram complete

I have the clymer service manual for my C10. I have always been disturbed by the fact they have a separate wiring diagram for the junction-box (fuse box/relays), on a separate page, with no hard cross reference to the "main" wiring diagram. This makes it hard for me to understand the circuit...

A previous owner had installed the aux lights so I am just replicating what they had done already. I am using an inline fuse wired from the battery. I also have a switch installed to control the aux lights. I discovered the relay that was originally installed with the lights had gone bad. I replaced the relay with the one from Murphs. It was wired into the bikes auxiliary wire so it powers on only when the engine is running. I've got it working - only to find one of the LED's is bad. New one's are on order...
 
It was wired into the bikes auxiliary wire, so it powers on only when the engine is running.

Is this kit the kit that Murph sales for the headlight "and" Aux lights?
Or, is it a kit that is "just" for the Aux lights?

My first note was based on his Headlight/Aux light kit.
In it, the power for the Headlight and Aux lights came directly from the battery to assure maximum amps to all the lights.
Power for switching hi/lo came from the OEM headlight switch.
{The OEM headlight switch made it work only with the key on}.
It put's minimum amp load on the OEM Headlight switch.

On Aux Light only kit, the Power for the lights should come "directly" from the battery, and switching on/of is done from the auxiliary wire to make it keyed power.
The Direct power gives you max amps to the lights and switching is done from the Auxiliary wires to place minimum Amp load on that circuit.

This sounds like what you have,

Ride safe, Ted

I have Murphs headlight kit installed. What is the pigtail for that says aux lights?

The Murph's kit I bought is just for the Aux lights. Accessory Relay With Pigtails. https://murphskits.com/accessory-relay-1/ It fixed the problem but I discovered that one of the LED lights was dead. :confused:

After searching online, I found a set of lights identical to the ones I am replacing. The new set come with the wiring harness/relay and on/off switch. Ships from France for $83.88 including shipping/taxes/etc. Lots of other lighting upgrades also available for the GTR1000 Concours. I picked up the LED rear brake light bulbs and they are definitely bright :cool: Wish I had found this option before I went through the trouble of rewiring my old aux lights. The harness that's included is really sweet, but I will have to wire into the old aux light switch since there is no room to install the handlebar mounted one that comes with. Which is ok since it is a lighted, rocker style switch which was mounted into the dash consol by the previous owner. https://www.ledperf.us/leds-and-xen...-for-kawasaki-gtr-1000-=c=-987_1564_1625.html
