Viking 0 Report post Posted May 18, 2004 I've just been informed of a cheap E30 320 manual going locally, not sure if its worth looking at. Most people who do the M50 converison use 325's but I was wondering if going from a 320 would still be the same. How much different are the wiring harnesses between a 320/325? Do they use the same harness just different ECU or chip? Quote Share this post Link to post Share on other sites
