I still miss my V6

The worst affected area is the relay holders themselves. The wires corrode and fall out.
Engine harnesses aren't available from FIAT any more, discontinued.
My solution was to cut some fresh relay and fuse holders out of the dashboard of a scrapped FIAT Bravo, being inside the cabin for 10 years they may as well have been new, cut them with as much cable as you can get. £20 from the scrap man for me, with some other bits too.
Cut the original ones off and the wire back till I found good wire, and stitched the new parts into the loom. Used heat-shrink to seal the joins, plus a lot of electrical tape and that plastic sleeving stuff.
Works fine now, and the engine runs better as the sensors are each getting a smooth 5V from the ECU now. Previously I had a hunting idle.
