Getting screwed for $18,000

Here in England, the lights must be converted to meet UK specs. The garage that converted my lights wired in a bunch of relays, and extra lights to make the conversion work. This overloaded the Smart Juction box located in the passanger footwell over a period of a year. Not knowing better, I took the car back to them, knowing their conversion is what cause the damage, and they would honor their work. They had the car for over 11 months,trying to fix the issue.

Long story short, when I went to pick it up, they said the installation of my VORTECH Aftercooler, is what caused the issue with my SJB, and charged me $6000. I just found out that there are about 30 05-07s that have had the same problem with their SJBs here in England which were wired almost identical to the way mine was/is. So between the bill they stuck me with, buying another car, insurance, and the car note, I am out well over $18k.

Do any of you guys have issues with your lights, instrument cluster, or any other electrics after installing other parts?

They did not fix it, they wired it up the exact same way they did before, its just a matter of time before it blows again. I took all the bad parts ( a complete wire loom, & 3 SJBs) with me.

Which company are you referring too? I took it to AMCAR, and they will go to court with me, that is not my problem. My problem is that I need to know if any of you guys are having issues with your electrics after the installations of blower/aftercoolers and such. This will help with my court case.
