The FACTORY relay USES ONLY 4 Pins----TRUE, but it IS a 5 PIN receptacle PLUG for the relay with only 4 wires going to it and a blank area for the 5th pin to fit. ALSO, the 5 pin BOSCH relays used in both the factory and NORMALLY the bypass have TWO (2) 87 Pins (87 and 87a) which are obviously the same so only one is used. It is actually just a 4 pin relay configured with 5 pins for optional mounting plug situations. Again,ONLY one of the 87 pins is used.
I can provide a wiring harness pic of the 4 wire, 5 receptacle plug if you are still in doubt. 
Not being confrontational--just accurate.

Thanks, Lee!
The reason for only 4 wires would be that that particular 5 terminal relays function requires the use of only 4 terminals and is not even relevant. The extra terminal is the way of running the start circuit through the normally closed relay points to complete the desired starting circuit path, of course that has to be one of the only 4 terminals that are used. Naturally, as you know, the Bosch 4 terminal relay will not work in that situation.
