I'm in the process of doing my gen 3 turbo swap into my '91 jdm sw20 turbo.
There are a couple of wires i'm not sure about in the 8 pin fuse box connector.
Pin 6 (blue wire) needs to go to pin 1
Where does the blk/red wire go which is already in this location?
Where does the blk/red wire need to go which is in pin 5 as their is no pin in the fuse box for this to plug into?
 
Any suggestions would be greatly appreciated

Ok I think I've worked it out.
Both blk/red wires need to splice into pin 4.
