Another Obc Question
I have to ask since I can not find anything about this on here. I did see on bimmerdiy.com that to do a OBC upgrade that you had to get one out of the same year and make as the car you wanted to install one in. I have just picked up a 1991 325i without an OBC and have a loaner 1987 325is that I can get everything out of. Question is will it work in a 1991 325i. I really didnt want to go through the work taking this one out if it will not work in a 1991 325i. Any help will be appreciated greatly.
