Wiring issues on a 53 STi

[Impreza abuser]

Good afternoon 

 

I have just stripped out my Impreza and fitted a cage. I have just refitted the dash/clocks/loom but have two issues.

I have no side lights only at the front and also no front/wing indicators and seem to have a plug left/ It is by the fuse board.It is a white single layer plug as shown with power to thr middle two terminals

Can anyone shed any light or info please

 

Thankyou in advance  Simon
