I cover 3 4 and 5 pin relays and all you need is a 12v source a multimeter and a test light. The terminal widths used on 4 and 5 pin relays are almost always 6 3mm wide however some more specialist relays can have terminal widths of 2 8mm 4 8mm and 9 5mm. A 4 terminal relay is used so a low power circuit may engage a high power circuit without risk of damage to the low power control circuit. For example a low power circuit in a car that commands the high power headlights to come on would send the command through a 4 terminal relay.
The 9 5mm wide terminals tend to be used for higher power applications such as for starter motor solenoid activation and the smaller terminals tend to be used for electronics signalling where only very low currents are required. The difference between a 4 and 5 pin relay is that a 4 pin relay is used to control a single circuit whereas a 5 pin relay switches power between two circuits.
