HGV Auto electrician needed - Manchester

Looking to get some additional reverse lights put on the truck and need a knowledgeable auto electrician in the Manchester area.

I’ve been told the modern Actros can be very skittish when new electrical items are installed if not done correctly. This is how it was explained to me - “yeah, if it’s not done exactly right the ECU sh*ts it’s pants and puts the truck in limp mode if you’re lucky”
