Pin3(Y4)- Blue - Outside temp sensor
Pin4(Y5) - Black - To F15 (15A)
Pin5(Y1) - Red - To F12 (20A)
Pin6 - Green - RPM signal
Pin7(Y7) - Grey/Yellow stripe - Instrument Illumination (dimmer controled)
Pin8(Y8) - Red/Grey(white) Stripe - Radio (aerial power feed i.e. Radio on indication)

Pin14(Y14) - Brown/White Stripe - To pin 8 of diag connector (to support programming)
Pin15(Y15) - Black/Yellow stripe - To check control
Pin16(Y16) - Black - To F2 (15A)
Pin17(Y17) - White/Green stripe - To check control
Pin18(Y18) - Black/Yellow stripe - To check control
Pin19(Y19) - Yellow/Red stripe - To brake pad wear sensors
Pin20 - NC
Pin21(Y23) - Grey - To Auto transmission
Pin22(B10) - Brown/Yellow Stripe - Washer Level sensor
Pin23(B5) - Brown/White Stripe - Computer stalk buttons
Pin24(B6) - Brown/Red Stripe - Computer stalk buttons
Pin25 - NC
Pin26(Y12) - Blue/red stripe - Speed signal (from ABS controller)
Pin27(B9) - Black/Brown Stripe - ECU signal
Pin28(B3) - Brown/Blue stripe - Coolant level sensor
Pin29 - Black/Violet Stripe - To Hid lighting
Pin30 - To Diesel fuel pump (X20DTH only)

The rpm signal (green wire on the one plug version) had to be taken from the clocks, otherwise fuel consumption didn't work... also the outside temperature was not correctly displayed (temperature readout started to climb from about 22 c to 69( in autumn :) ) till it showed F at last ) swapped the wires so it works perfectly now.

Worth its weight in gold!

(being digital information I suppose it has no mass, so no weight, strictly speaking that's an insult!  :D)


Thanks to Mark and yourself annihilator  :y

Doctor Gollum:
Also a guide on here for retrofitting Mid to Tid equipped cars :y

annihilator:
only 2 years on and still trying to sort this  :D
"Pin28(B3) - Brown/Blue stripe - Coolant level sensor" is incorrect should be pin 20 on the grey plug to pin B3 on the black plug.

Also having no luck with displaying fuel consumption/range etc. which is presumably handled by this
"The rpm signal (green wire on the one plug version) had to be taken from the clocks, otherwise fuel consumption didn't work" I presume this means connect the green direct to the green on the multiplug behind the instrument pack which I've done but still get the F in the MFD.
Anyone got this working?
Cheers John.
