Compatibility Question EWG on PWG -
05-03-2021, 10:49 PM
Hey y’all, got a quick question. I’m looking to buy a friends JB4 tune he had on his ‘14 528i (EWG) and I’m looking to get this for my ‘13 528i (PWG). I understand they’re different but does the JB4 include wiring for both EWG and PWG or is it fitted with one or the other? How would I be able to decipher if his JB4 box has the cable I need? Any insight is much appreciated!
