Help identifying brown connector

[huggys-customs 0]

I've just put my 1986 205 gti back together after taking the engine out during lockdown.

 

I can't see where this plug connects to.

 

Can anyone help? It's below the coil and distributor. 

Its only 2 pin but has 3 wires in it.

 

I've looked through the forum and can't see anything similar in all the pics from others in similar situations. 

 

I'm having trouble getting it to idle properly, so hoping this is the cause. It starts and idles at 2.5k, if I blip the throttle it tries to idle around 900rpm and stalls. I've checked timing and tried to set the tps and idle screw. Then I found this connector.

 

Thanks in advance.

Thanks for the quick reply. Is that the silver thing mounted on the top of the strut tower? If so mine seems connected already. I think, I'll get a pic when I get home.

Thanks

No that's for the dim dip lighting, but looks very similar.
