I bought my MDX about a year ago and the seller told me he unplugged the HFL because it drained the battery. So what did I do? Reconnected it...then had to have my MDX jumped the next day. So obviously I need to replace the HFL. Has anyone replaced there HFL and had success? And, does it matter which edition of the HFL you install? Meaning, if I pull a HFL from an '07 MDX in a junk yard, will it have the same issue?
