skinny 'relay' (its pictogram sensing box) and wide hi/lo relay box. Check our past posts. Lots written on it. There has been trouble with production soldering of the heavier tabs as there isn't enough dwell time for the wave soldering machine to get the larger mass tabs and such to heat up to wet to the solder and it results in cold joints which will fracture completely after many cold hot cycles and physical jolts. The tall skinny needs the base to circuit board inspected old solder wicked (a way of sucking up molten solder to clean the area for new soldering) and resoldered. Use electroninc type solder 60/40 minimum not 50/50 plumbers crap. 63/37 is the best. Its Eutectic (no plastic state when it solidifies and a couple of degrees cooler at melt point).
