Lightbar & Reverse Light Wiring Harness Help

Hi,

I'm planning to fit a light bar and reverse light to my 2013 Jimny.

I've put together some wiring diagrams for each - could anyone let me know if they look right?

I'm planning to use 25 amp wiring throughout.

I assume the 3 terminal switches are because one terminal is the illumination bulb, and that you want the switch to light up when the light bar or rear spot is on.The reverse spot will work, but the illumination terminal of the light bar switch needs to go to live, I'd take it to the feed to the light bar as shown. 

 

If it suddenly breaks, go back to the last thing that you did before it broke and start looking there :)

TBH if you are just fitting LED reverse lights no relay or extra wiring is required, it goes through a manual switch in the gearbox



Obviously if you are going the old style spots then a relay is advisable, but 30A is a lot of draw, I would have though a max 10A fuse, or even a 5A depending on what you are fitting, 10A is still 120W or 2 headlight on full beam.

Thanks. Yeah I think it was a case of me going for more than I needed with fuses just for head room. I'll put a smaller fuse on it.

What would the harness look like for going into the gear box?

Actually I say that about the fuses, I did my extra lights at the same time as the towbar & fitted a towing bypass relay only because I had on in my drawer. So my reversing lights are on a relay, Sorry about that, but if I was just fitting those LED lights I wouldn't have bothered, I'd have just teed into the reverse wiring at the lamps or somewhere down the right hand side where the cable runs.

My parts finally arrived so planning to fit this week.

Pretty new to electronics, so just got a follow up question on the switch if that's ok?

I've attached the diagram for my switches:


LIGHT BAR
PIN 1 goes to headlight negative wire
PIN 2 goes to relay
PIN 3 goes to light bar

REVERSE LIGHTS
PIN 1 goes to reverse light positive wire
PIN 2 goes to relay
PIN 3 goes to ground

That is correct, I labelled them

PIN 1  Feed
PIN 2  Load
PIN 3  Lamp

You want 12V across the tell-tale lamp when the lightbar/reverse lamp is on.

If the tell-tall for the light bar is on all the time, the switch is not as drawn, and you should move PIN 3 to the positive side of the relay. You could just take P3 to the positive side of the relay anyway, then the tell-tale comes on when the relay operates- You'd notice if the light bar wasn't on.....

And as suggested, drop the fuses to 10A.

If it suddenly breaks, go back to the last thing that you did before it broke and start looking there :)

Lightbars are all set up, thanks again for the help Facade!

Ran out of time today for the reverse lights but will look at them tomorrow.

For the gear box reverse light switch, what's the best way for me to check which is the positive cable to splice into please?
