First of all there is some hidden information before you buy this item. It is not mentioned that it is necessary to disconnect the battery for at least 24 hours (which is clearly mentioned when the package arrives. If it had been explained to me beforehand, I would not order this item and wait because it is painful for my Auto to remove the battery connector I haven't used it and pending in my backend auto Also the installation instructions are lax with lots of 'ifs' and 'buts' to less blame their product if If this is the case I plan to return it as is.
