Help Using Narva 63026BL Switch for Spotlight Wiring

[BA Baracus]

Hi,

I'm about to install a set of Narva Maxim 150's on the NP.
I understand all the wiring, earthing, fusing, relay etc and how to make up the loom.
I want to use the Narva 63026BL switch because it will fit the hole in front of the gear shifter nicely and will look good with the LED.

My problem is after looking at the switch it has 4 pins - see pictures attached:
Pin 1: Power
Pin 2: Ground
Pin 3: ACC
Pin 4: Relay Switch (opt)

So am I correct with my thinking that:

Pin 1: Power
Pin 2: Ground = Earth (obviously)
Pin 3: ACC = Connect to something like stereo or cig lighter power so the LED switches on with ignition.
Pin 4: Relay Switch (opt)

I need to know whether to use
Pin 1: Power
or
Pin 4: Relay Switch (opt)
for the 86 pin on my relay, it may be obvious to some but is Pin 1 for use if you do not use a relay?

I would appreciate the input.

Thanks

I'm pretty sure its:

Power -> Acc is the contact that gets turned on and off (e.g. in would go form the high beam trigger to the relay.

Ground goes to earth to allow the LED to illuminate when the switch is on.

Power = Supply
Acc = Load
Ground = Earth
Relay Switch = ?

Maybe wait for someone to clarify, but I can check with a multimeter tomorrow as I have this exact switch in the shed.

Pin 1: Power = Power from high beam
Pin 2: Ground = Earth for LED
Pin 3: ACC = High beam feed back to relay
Pin 4: Relay Switch (opt) = not sure

That's how I do it for spot light switch, but there is more than one way to skin a cat

So what powers the led in the switch?

So what powers the led in the switch?

The LED is only illuminated when the switch is turned on. It gets 12v from the power source input (eg high beam) and then uses the ground pin to complete the circuit.

Got it, thanks heaps, but we still don't know hat the 4th pin does!

We fitted one of those switches to my brothers NT (MoreliaMatt) and could not work out the internal workings of the switch to get the LED to illuminate when the spotlights were armed.
We emailed Narva asking for a wiring diagram of the switch internals and they replied that they didn't have this info and pretty much had no idea how the switch worked. Hopeless....
Anyhow, the switch is in and just working as a plain old dumb switch. Couldn't work out how to wire it up properly, so the light is not being used.
Not much help to you I know but thought you would be interested in the story.
Cheers, Dan.

Hang on a second, so if I turn on the Narva switch it only illuminates when I flick the high beams on?

I have the same switch, works just fine wired as below:

Power = HB in
ACC = HB out....to relay
Ground = Earth...... to close the led circuit and make it illuminate
relay switch optional....not used.

which is exactly what BB said.


When the switch is off, all poles are open.
When the switch is on power and acc is closed, allowing HB voltage to pass to the relay (HB has to be activated of coarse). It also closes the circuit between power and ground to illuminate the led.

Yep. Its an indicator that your spots are on if you're blind and cant see em thru the window.

Thanks guys, I may be coming back with a solution.
A mate of mine has had a look, drawn up a schematic and will do a
working mock up in the next week or so. He works in Avionics. Planes aren't that much different to cars are they?

[BA Baracus]

Success!!

Hi Everyone.
It can be done!

Turn switch on and LED turns on independent of high beam and remains on when HB selected and spots on.

See attached wiring instructions.
And photo of my blinding spots.

Hope this helps others, as this forum has been great for me.

Well done!

Might have to go have another look at mine now to get that LED lighting up!

So just confirming:

Switch Off = LED OFF
Switch On, High Beam Off = LED ON
Switch On, High Beam On = LED ON

well done to your mate, hope i can get mine working now!

It seems that it can be done Matt, but we will need to modify your Lightforce wiring loom.

As per diagram from BA Baracus (and as I have the spotties wired up on my Paj), you need to switch the earth feed for the spotlight relay and feed the high beam trigger directly to the relay. This is also good as it only requires 1x wire to be fed through the firewall. The earth feed also gives the indicator light within the switch an earth circuit.
The lightforce loom switches the high beam trigger and runs the earth direct to the relay, meaning that you will never have a true earth at the Narva switch on your dash. This explains why we never got your switch working properly....

I my previous cars, I leave the spot light switch on all the time, so when the high beams are activated, so are the spots. I thought this was common practice with most people?

If what is described in previous posts is correct, then the LED will be on all the time as I always have the switch on, right?

I alway thought it best to feed the switch form the high beam and then to the relay for the spots. Also on the switch its just a matter of earthing the ground wire to make the LED work. At least that's how I did it in my old car. The switch can then remain on and the LED only activates when the high beams are on (and the LED subsequently illuminates).

I think I must have missed something along the way here.
