Default Fuel pump prime wire question

This is an engine swap question, hoping someone can assist, pcm and motor from a 94 formula, following the pictures on shoebox site and lt1swap, I have wired up the fuel pump relay using the white c220 plug, however I am now seeing a fuel pump prime load in the area of the c100 connector, can someone tell me where this goes? Does.it just tie in to the relay as well, giving power before starter engages???
thanks in advance
Darren
edit, after spending some time on Google, it looks like nothing plugs into it, it's there as a way to prime the line manually, does this sound right???

Correct, nothing is normally connected. The fuel pump prime lead is there for manually running the pump.
The pump will run as long as 12V is applied, as compared to the ~5 seconds you get by turning the key.
