Make sure you receive a quote in writing. After asking the specifically about the inclusion of the 12 pin plug, I was told the $500 complete for the electric brakes system on my car. I even left the wiring diagram from the caravan company on the front seat of the car for them. When it was time to pay for the job they informed me that there was no mention of the 12 pin plug and that was going to be extra $220. Good job but staff are liars. I would use someone else.
