Anyone install Fog lights using a battery tender cable?

[StratTuner]

I went back and re read.... OK... a relay is there to interrupt the circuit even when the on/off switch is on. That's convenient. Makes it impossible to leave the lamps on when the key is off.
I have that problem with the GPS circuit as it has no relay. If i leave the gPS plugged connected to its USB port, it will drain the battery even when the key is off.

I think I'll leave the relay out as it would require tapping into the existing electrical. I've done that under the rear seat where electrical is easy to get at.
It's not easy to get at near the headlight.
Thank you all for pointing me in the right direction with this. I did read those things the first time, but I hadn't thought about it enough yet to process the information. A long walk to Starbucks fixed that.

I think you are making it more complicated then it is:

I think the reason you want to use the tender cable is because you dont want to cut or tab into any wire in the NC.

you need this:

OPT7 8ft on Off Power Switch for Off Road LED Light Bar Relay Wiring Harness | eBay

or something similar.

this cable will allow you to tab into the battery directly and control the with a power switch. no cutting wire on the bike


this one is cheaper and has it for two lights. check out the diagram - easy to understand.

Interesting set up but the problem remain, if you forget to turn off your light, your battery is dead … like mention in other post, anyone can forget to turn them of … Hapened to me 2 days ago…. The set up is directly on the battery (installed by previous owner….So where can I connect the negative of the fog light switch in order for them to turn off when key is removed on engine shut down? There is no place to connect it on the horn or other element in the fuses box ….

Also what are tender cables ?
Thanks you very much for your help guys . I don’t want to be stuck again for a poor set up….

Speaking of dead, this thread is 10 years old...

Any electrical accessories should be routed through a 4-pole relay so it gets turned OFF when the ignition is turned OFF. It's simple to do but most people skirt around it.

Got it. Thanks. There is a relay whit the fog light installed directly to the battery. I guess I just need to re connect my power switch wire somewhere else… I thought about the 6 pins accessories harness but I have 3 pins and only 1 pins supplies power, but poor power… 4,93 volts engine off, engine on 5.6 volts at idle ! What is that harness for if 2 out of 3 pins doesn’t have power to it and the last has so little!

You would probably do well to get a service manual for your bike. It could help answer many of your questions.

On NCs with LED headlights, if I remember correctly the 5 volts DC output is an indicator of high/low beam headlight status. It is not a power output; it can be used to trigger functions on auxiliary lights. A proper service manual could explain for you the purpose and functions of the accessory harness pins. I cannot answer the question with certainty because I do not own a late model NC or it’s manual.

Edited to add: Here is a thread where the 5 volt output on the accessory harness is described and utilized: https://www.nc700-forum.com/threads/auxiliary-lighting-for-2018-nc750x.16641/
