thanks tony. i spoke with steve and he gave me a good deal. but he said that if i find a good cable in a good condition, i could use it. i went to the junkyard, got the egr pipe for free, but no luck with the wires. however, i saw that this is actually the same wire that goes from the alternator to the mega fuse and then to the battery. and then it all became clear to me.
the guys that fixed my megafuse 5-6 months ago zip tied the cable to the coil pack. those ties broke, and the whole cable got loose. it fell down to the egr tube and burned. the guys said that the car is likely to burn if driven, but they don't want to take any responsibility of their prior work. they will check it again, and let me know if they will fix their mess...
