If you live in Canada or a northern state, check for a heater in the block. It may already be there with the plug tucked away somewhere.
For several years, Rangers originally destined for dealers in Canada, AK, MN, ND, SD, WI, WY and MT have been getting block heaters as required factory option 41H. Since it is the same truck under the skin, I would think that the Mazda B-series has the same requirement. Of course, if your truck was originally purchased in another state, it may not have that option.
