Rain sensor/Auto Mirror/Tuning box retrofit

[yysnet]

Sorry title is a bit longer...

Auto mirror:
In the forum there is a how2 on auto dim mirror, however i think £40 for a cable is too expensive.
There are only 4 wires in the mirror, which are located in PIN 1,2,3 and 4 of the connector. Can somebody point out that what are these wires for?

Rain sensor:
I got this sensor, as in the picture. As per tis says, only PIN 1,2,3 are used.

Auto headlight:
The day/night sensor is integrated in rain sensor or auto dim mirror?
Headlight switch is not a problem, will modify "0" to Auto and post here later.

Tuning box:
Going to start with a mod on common rail pressure sensor, the connector looks like the picture below, can anybody suggest where to source a matched male plug?

Thanks all

Pin 1 and 2 is for power.

Autolights are controlled via the rainsensor.. (the sensor marked JL dont have a lightsensor, and prefacelift dont ahve the option of autolights)

Thanks.

I work out PIN 3, Grey is normally at 12V, which will cancel the dimming if grounded.

PIN4 is reverse logic of PIN3, is normally at 0V, which will cancel the dimming if connected to 12V.
