Surely the selling dealer can solve this, it’s a very simple and minor job. All it needs is a request for them to prepare the car for your battery conditioner as part of the PDI and prep. Assuming you don’t fancy doing the job yourself, all the harnesses and connectors are readily available. Give me the measurements and I will knock up a fused sub harness for you, done that for a few owners on here.
