Your towbar will have to be type approved but the electrics are fitted independently. Most Vauxhalls include a 9 pin connector under one of the trim panels that need removing for the towbar bolts BUT Vauxhall dealers are the only ones who sell a kit with a matching connector. I've tried Tandy, Maplins and Radio Spares to identify the connector without success. I always end up cutting the connector off and using electrical connectors of the correct ampage. The battery supply cable will normally only become live when you fit a fuse in the holder marked trailer. Although there is a trailer warning position in the dash cluster, it probably has no bulb fitted.
When fitting a towsure type approved towbar to my 98 vectra I asked at my local dealer if they had such a connector as my Haynes manuel hinted at one in the electrical diagrams. The dealer told me that they use the blue snap lock style crimp on conectors like the rest of us (available from just any good auto spares / electronics shop see Maplins part number AR21X for a picture.
If you do not have a wiring diagram you can check each wire by using a test bulb with one side grounded and the other attached to a pin which you can @!#$ through the insulation to find which wire into the cluster does what, aulthough this technique does require a helper to operate the lights.

Re: Vauxhall Zafira Towbar Elecrics -
First the Bar must not only type approved must have a TUV mark for europe travel .Connectors for just about every car are available .BUT DO NOT FORGET when fitting a 13 pole (now the standart the power lead for AUX trailor electrics such as battery ,fridge etc must be taken direct direct from the battery and have an in line fuse .This cable is not in the car wiring loom.
HJ is very correct, somebody tail ended me in Germany my Disco had a UK supplied tow bar from Land rover but was not type approved or a Euro tuv mark I was blamed for 30% of the damage and my insurance would not pay my share..
