I am wanting to fit a towbar which looks simple enough but am confused about the electrics.

From one of the ads it asks a question:
Do I need a bypass relay kit?
Vehicles fitted with bulb failure devices or cam bus systems and LED systems will require a bypass relay kit. A 7 way bypass is designed for vehicles which have Multi-plex wiring, Cambus systems or Bulb Failure devices which where introduced around the year 2000. This bypass prevents any faults on the towing vehicle's light system by switching power directly from the vehicle's battery/alternator to the trailer/caravan light system, using very small signals from the vehicle's light system, without the vehicles check control sensors system being adversely affected. If your vehicle has none of these you will not require a bypass relay kit. Please call us if you need clarification.

My focus is a 51 plate 2002 diesel 1753 engine estate

How ca i tell if it has or has not the above?

im sure the older focus doesnt actually need the bypas relay, i fitted one to mine but another guy on here didnt bother and has had no probs.

i know it's not a focus but the wiring/systems will be similar. i never put a bypass on my fiesta for the electrics and i've not had any trouble since and i've had camping trailers right up to caravans plugged into it and nothing has gone wrong.

Thanks - just fitted my tow bar and electrics - the towbar was easy enough - the wiring made me nervous but I didnt have to be as the instructions that came were very clear and a quick call to the manufacturer helped me realise its not so difficult - went for the single socket for now as i have a folding caravan - can add the other socket later if i need to.
Price inc delivery £76.95 and they gave me a 5% discount off my next purchase which may be the other socket and the code lasts for 6 months.
