Ah - that will be from the loom that goes under the rocker cover. I bought a 2004 TD5. 130K. So far it has cost me an additional £3k odd on top of the purchase price to keep this money pit on the road in the last 10 months. Started with leaky sunroof (sealed shut), window mechanisms (replaced), ECU loom, fuel pump, injector seals, ACE pipes, suspension airbags, front calipers, ignition switch falling to bits. I wont bore you with all the niggly bits that have packed up or fallen off, but now the ACE block is leaking, looks like a need even more money, just so that I can get rid of it with a (fairly)clear conscience. I bought a Pajero to run around in whilst this was in for repairs - it cost me £900 and hasn't missed a beat.
