tow bar wiring
 

Hi all can anyone tell me if it's ok to wire the tow bar wiring straight onto the loom in the boot of a tourer without going through the relay box that generally comes with the two bar thanks in advance

Are you wiring for a caravan or just a trailer and only need road lights?
In the UK we need to know if the trailer indicators are working and the normal relay gives an audible sound.

Why do you not want to use a relay?

i fitted the tow bar myself but didn't want to attempt the electrics so i got a friend to do it and left him to it when i got back he had wired the tow bar but the relay was just lying in the wheel well i would have prefered it had been fitted is there much involved in fitting it

No not really. You should run a power cable from the front as only minimal power is taken from the harness. This small amount of power is detected by the relay and it uses power from your new power cable to provide power to the road lights. I am not sure where my handbooks are as I am in the process of moving house otherwise I would tell you which fuses on a Face Lift fuse box I used

Not knowing which relay you have but a TEB7AS is quite common, this link shows how to wire it

thanks for your help macafee2 the the tow bar i have fitted i got on ebay it'a from a rover 75 and the relay is a PCT LOGICON ZR2500 it looks like the one in your post narrower and longer but all the wiring looks identical i may have a go at fitting it as i said i would have prefered it albeit it is just a little trailer i have but you never know when something else would be getting towed your input is very much appreciated George
