Trying to fit electrics to Ford Focus Hatchback, Titanium model. 2010.
Have looked at mass of electrical cables around boot area and have decide to buy a "vehicle specific" kit but have not been able to locate one.
Can anyone give any advice please.

Have just had a bad day. Left lights on overnight and battery flat this morning.
Tried jump starting with friend but lots of messing with poor contact thro cheap clips them "Engine Malfuction" come up on dashboard and refused to do anything after that.
Called Direct Line Breakdown man, he very quickly diagnosed broken (short/cell out, whatever) battery. He also gave very severe warnings about not jump starting modern cars and said there could be further very expensive damage.
Gave me choice to go and buy a battery or pay cash £80 for one from his van. Choose to buy his, just to keep his goodwill and save time but started to worry as I went to cash point "is this a con". Decide I would keep old battery so could carry out my own check later but breakdown man said it was an exchange deal only. After new battery fitted he then appeared to have lots of problems resetting engine malfunction and said problems connecting to car ECU, I was getting VERY worried. But he then produced a bigger looking control unit and proceeded to re-install the car software. Much to my relieve the car started and all was well. I was £80 poorer but at that point in time I would have paid a lot more to get the car running. He said if the ECU had been damaged it could have cost £1800 so I was very pleased to get away with £80. Two questions:-
1) Was I conned, many facts of the case appear to indicate a possible con, but is this likely from a person contracted by Direct Line. Note his van had no marking, but he seemed very professional in his approach and communications with me.
2) Is he correct when he warned me NEVER to jump start with this car (or any modern car), he recommended buying a Power Pack for the regular jump starting of my son's car.But a power pack is just a battery so what is the difference.

Any views

I have successfully refitted the Towbar taken from my previous Mk2 onto my Mk3 but now have to face the electrics. Does anyone know if their is a dedicated socket on wiring loom for Towbar electrics.
Otherwise my only option is "knive & fork" attack on wiring using those scotch(?) connectors things. Would hate to do botch job only to find out later that a dedicated socket was available.
Any other advice would be welcome.
