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.

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.

What year is your car?

 Guide was written on an '54 3.2.

If pre or mid facelift, then use the wiring diagrams in Haynes :y

I'm using Haynes which is how I spotted the coolant sensor difference it's the f fault that has me stumped as the info seems to tally with what's in Haynes.
It's a '97 2.5V6 manual.

Early pre face-lift mfd's had a yellow and black plug which suffered with pixellation with age hence the swap to later single grey plug type which doesn't. If you'd read the full wiring list you'll soon catch on. Head unit is of no consequence.

Ah, OK. Makes a bit more sense.

Is the green on the back of the instrument cluster at Pin 22?

Also how are you swapping the plugs? By moving pins or joining wires? Be mindful that the pins aren't a great fit iirc.

Have just had a look at the diagrams. All you can do is list the pinouts for both types and cross reference them.

The guide here is of limited use as it is to swap from a TID (yellow plug) to a late Mid (grey plug).

So go back and cross check every pinouts. Can't be much more help without actually being there.

Did this a couple of years ago on my 94 opel omega mv6. Also had the coolant level problem until i changed pin 28/20. The old pins locked OK in the new connector when i bent the pins locking tabs a bit extra. Had to change fuel sender and instrument print plate in mine as the 94 and some 95 cars have a different setup for fuel sender. Shouldnt be a problem on a 97 car though. Got Opel to program the new mid to the right engine/gearbox and wheel size and everything worked great. Mid must be programmed  according to the age of the mid and not the cars age. So in my 94 car i got them to program the new mid to a 98 3,0 auto.

Hi,did you change the sender in the fuel tank and was it the pcb or fuel gauge you had to change.
A few pics of what I've got

 

top ones green pcb are the '97 V6 whilst the lower blue pcb is '98 mini-facelift
if I fit the mini facelift pack the F fault seems to disappear but the warning lamps either don't work or come on for the wrong thing.

Thanks John.

Don't get long to edit your post  >:(
Anyway forgot to mention when using the mini facelift instruments I got a figure in the range display not an F.
