I've just been given a towbar for my estate, it has twin electrics, but no plugs on the vehicle end, anybody know where i can get plugs to fit the omega and in fact does the omega harness support twin towbar sockets?

it's the plugs that fit into the Miggy's harness I need, it has the trailer sockets (one black and one white)

Cheers for the link I'll have a browse

I don't think you'll find those unless someone was rich enough to order a factory fit towbar, and even then you'll only get the 12N. Just use the socket wiring to get your connections from, but be aware that the brakes (black/yellow) at the socket won't suppply the brake light direct. It's wired from a trailer brake check control 'relay' which fits behind the glove box on face lift cars & above the driver's feet on PRE face lift cars, the 'relay' is/was about £16 If you seach hard enough on the forum, you'll find the part number - i posted it - but god knows where.

there is i was looking at it a while ago, but I seem to remember that the Miggy estate had a dedicated connector behind/underneath the tailgate slam panel trim (if that's the correct term for it) and wanted to know where i could get the towbar side of that connector from.

sorry if i'm not making myself clear enough

so do i have to remove the slam panel trim? or can i get to it by just taking out the spare wheel?

Neither just open the lid and they are tucked up the left hand rear corner.

I'm still sure we have the Omega loom/12N wiring colours somewhere ... 

I've got to take the towbar off the gold 2.2 so I can do a colour to colour chart for the maintanence section

And I thought it was gonna be just a case of bolt, connect and drive... I should have known better 

I have been following this thread with interest because I will be needing to fit a towbar soon and I would like to do it the 'factory way' if I can.

If I have understood correctly I should find:
1. a prewired socket in the boot (with link plug in for the fog lamps)
2. a 4 pin indicator relay socket with a 3 pin indicator relay fitted
3. a lamp holder in the instrument cluster (wired to the 4 pin indicator relay socket) ready to take a 1.2w warning lamp
4. a socket for a trailer brake failure relay (that is capable of bringing uo a message on the MID).

Am I close? I am thinking that the only awkward items to source would be the trailer brake lamp failure relay and the plug for the prewired socket in the boot.

Yes!
I wouldn't think about the GM loom/plug to plug into your (round) socket, just use the wires to link from - don't use Scotchlocks though    You'd need the 8 connector GM 12N socket to go with it - mine came from Dr O and was one knocking about the workshop from an Astra.
The trailer check control 'relay' part number is above.   

I have a 230v 780wats ( Not 240v ) lead out for caravan on mine, it's located in the rear pas side wheel well, bloody good keep frige going and the clooks going as well in side, allso charges the bat in caravan.
