Hadn't thought about the bypass relay, but perhaps one with the winker buzzer integrated might be a good idea........

You don't need a by-pass relay. Just swap the 3 pin indicator relay for a 4 pin & put a lamp in the dash. Buzzers are annoying!

OK thanks everyone, some food for thought there. I have just a few more qs please. Is a Westfalia tow bar any good?

If I got a twin electrics kit, without a bypass relay, what would happen if I plugged the lights and the fridge in? Would it flatten the car battery by powering the fridge after I had stopped the engine? So I could just get round this by unplugging when I stop the engine?

Thanks

The bypass relay is only for the vehicle lighting circuit,the 12 s socket uses a split charge relay to look after the fridge 12v operation and caravan battery charging

Eh! I'm confused now! I know nothing abut electrics. Is there a resource anywhere where I can find out about it without being fleeced by a towbar fitter. Tried searching Yahoo but as usual all you get is people trying to sell you stuff.

Thanks

Don't be confused about electrics. By-pass relays are on the market to be used on cars with fancy/complicated electrics to the backlights. The Omega is pre-wired for a trailer from factory with a socket in the boot behind the trim at the very back of the boot, (almost ) all the wires you need for a 12N (trailer lighting) are at this socket. Theory says that you should be able to buy a loom from Vx to plug into this but the theory fails when you try to get one. Just use the wires from this socket to supply your 12N socket. 12S sockets are a little more complicated, but all you are ding is supplying 12v to your caravan's battery & fridge when your engine is running. Be careful though as caravans from before 98? are wired slightly differently. Google is your friend.

Thanks AndyB I think I've got most of it sussed now after some research today!

12n for lights, less reverse.

12s for reverse and fridge etc.

I need a bypass relay as the Mig has light check system on. I also need a split charge relay so the fridge etc doesn't flatten car battery when engine is stopped?

All in all I need, tow bar, twin electrics (12n and 12S), bypass relay and split charge relay?

Thanks

[size=16]You don't need a by-pass relay!! [/size]

but Yes to the rest 

Kevin posted various links recently that gives locations & part number for trailer check control if you want to fit it or what to bridge if you don't.

Ah right sorted, got it now! I don't need bypass relay as it's prewired for trailer, I just connect to 12n socket.

I'll look for thos posts now!

Thanks Andy B!

Correct! Just be careful which blue/black/rear fog light wire you use though, it's intended to be used with an 8 core cable & a 12N socket with a switch inside so that when you plug your caravan in, it switches your car's rear fogs off to prevent glare in your review mirror. (In all the miles I've ever towed, I've never had to tow in fog  )

Thanks, i found those posts from Kevin. I'll just follow the instructions off my towbar when i get it and hopefully it'll all turn out ok hahahaha
