p100 2.8i V6

hi there everyone, i have a problem with my lights, fuel pump and dash lighting.. i had a little poke around and found the fuses are fine but it appears monkeys have been at the wiring, cutting bits here, stuffing them there etc... wondered if anyone had a full wiring loom complete with ecu's for sale? also 2.8i clocks and speedo cable would be very welcome... 2.8, with no rev counter?!! :/.... the engines from an 2.8 xr4i if it helps
