rear led wiring

[bloat]

I need some help again please all now I have bought some led rear light strips and the idea is they come on when the rear lights do, so I have wired them up and nothing, there is only two wires red and black and I have put the black to black and red to green on the car right by the car rear light bulb and ideas why they don't work?? Thanks

Have you tested them across a 12 volt battery first?
Do you have a link to them, or any pics?
Were they designed for 12 volts?

Sounds silly I know but is it simply a polarity problem?

As Rustic says Just test it across a 12v battery.

Where have you wired them into back of the rear lights or into the main harness behind the N/S 1/4 panel:nenau On the main harness the tail light wiring colour is Red/Blue:thumbs if you have wired to the back of the lights put the black wire from the LED's to the chassis for the best earth as the black wire might not be an earth & the red wire to the live feed on the lights:augie the wiring colours change from the main harness to the the lights at the plug behind the rear bumper:doh TBH i'd wire them into the main harness as the connection will stop clean & dry

Test them, on 12 volts first, red to + 12volts, black to -ve of battery.

Then connect to the correct wires.

Brillcheers I will try this tomorrow I have run the wire down to the back of the light I have only done the drivers side at the moment so will try this tomorrow thanks again, oh but I will try across the battery first :thumb2

If you do take them to the main harness there is a huge grommet on the O/S behind the bumper which you could run the O/S light cable into the boot after making a tiny hole & you can run the cable (will need extending) across the boot under the plastic trim at the boot opening to the N/S to the harness, the N/S can be routed up by the wiring into the boot & earth them to the body there. The rear light wiring colours on the main harness are the downloads in the tow bar section:thumbs

Got some of these in blue for my rear foot well lights & yes red is your live & black is the earth:thumbs

 

[rustic]

I got some similar white ones, used them under the bridge that goes across our pond.
They seem to survive all weathers, been in over three years now, maybe four.:thumb2

Ok so they are completely doing my head in now! I have run the wire from the red/Blue wire in the loom and run the earth to the main earth point behind the N/S rear trim but still nothing I just don't understand?

Did you test the wire first to make sure its live when you turn the lights on?
If the leds are anything like some I have bought before then I ended up soldering the connection as a crimped/scotch lock connecter wouldn't work.

 

[bloat]

Hi no to be fair I didn't I will get my multi meter out later and test the bits.I have connected to also I have used those blue crimp type blocks which don't seem particularly good so I think I will solder them too one I've tested it

 

[jims-terrano]

Have you tested them straight across a battery yet?

 

[bloat]

Yes I've tested across the battery and they work lovely
