My 2019 Ford Transit Connect I believe has a smart Alternator. To wire up my Renege 40A DC - DC Charger I'd like to know the best spots to connect my NEG - terminal to the van's battery (I assume POS + will go on POS battery terminal), and most importantly, where the IGN Signal Wire should be wired to the van? Lots of info on the Ford Transit van, but little on the Connect. Thanks.
