Hi, I have a 2003 Octavia which appears to have factory fitted towbar and electrics. Socket is corroded so have replaced but no power coming through. For simplicity and to avoid having to mess around at the front end I was just going to connect the new socket in parallel to the wires supplying the rear light clusters. Can I get away without fitting a univeral bypass relay or should I go the whole hog and take separate power from the rear cigarette lighter socket? Just after a quick easy fix so my new bike carrier is legal!

Many thanks for any advice.

Hi Octaskod

Your post is slightly confusing in the respect in one comment you say there is no power and the other you are talking about a bypass relay !

so what socket are you talking about 12N, 12N, or are you talking about a 13 pin socket.

I fitted a skoda wiring kit and it did take a power feed from the rear cigarette lighter, however, it was too long ago for me to remember what it powered.

As RADIOTWO says, slightly confusing but I'm assuming it is a 12n socket as you state it is for a cycle carrier, this is the one which powers the tail, fog, indicators and brake lights

I've fitted a 12n socket to my Mk1 Octavia recently and didn't use a bypass relay, just scotchlock to cars wiring loom via an audible buzzer for the turn signals.

Not had any problems so far

Hi simon

Depends what you are doing, but you must never take a feed from a rear (or any for that matter) cigarette lighter socket, for 12S (13pin) wiring, as most are only rated at 120Watts (10Amps) some are 150Watts, but you need at the very least 30 amp supply.

the best thing to do is run a wire (something like 10mm2) from the battery to the rear and then tap off for the socket(don't forget to fuse it)

Hi Alex

The problem with newer cars is the Can-bus systems, I am not too sure when they changed, but as you say yours is ok, and poss because its older, but if you did that on a can-bus wired car, you could blow the ECU , and this is where the bypass comes in.

All we need is the OP to come back on and explain more

It was not for an auxillary socket, just the standard 7 pin and the wiring loom was the gnuine skoda article, thinking about it it was to provide power to the trailer hazard lights as the hazrad flasher unit in the MK1 was not sufficently powerful. The wiring loom had feeds that intercetped the connection to the back right light cluster.

"I fitted a skoda wiring kit and it did take a power feed from the rear cigarette lighter, however, it was too long ago for me to remember what it powered."

I want to do this to power the indicators and lights on a livestock trailer. It will be the basic 7pin socket. Did you just scotchlock it onto the power supply. If so then which colour wire?

Cheers
