Series 2 cluster in a series 1 Fairmont

[titan 4380]

I have a Series 1 AU Fairmont with a Series 1 cluster installed. Everything works fine including the installed Series 2 climate control module.
If I install a series 2 cluster, I have the following issues;
The range until empty does not display.
The oil pressure gauge reads zero and triggers a low oil pressure alarm.

Does anybody know a fix for any of these problems?

This might help but this is a standard AU II cluster low series converted to hight series

Cables removed from holder (1) and tag the wires (2) so they can be easliy seen.



Next use a loom from a high series to make the new connections. If you don't have a loom you can modify 2 Floopy drive power cable instead (Trim the sides to allow a smooth connection, cut and remove excess slots you don't need)



and

With the loom in place, splice with wires together.

Test and thats the lot

this goes first

[QUOTE=Uncle_Ken]I know this has been covered a million times but some of the main things have never been answered, I changed my AU3 Forte cluster to a AU3 Fairmont Ghia Cluster today, all working great, only thing is that i dont have a trip meter as the high series have it in the climate control? and havn't wired up the individual door ajar and the washer fluid senser

all the tec docs around give basic instruction on upgrading a series 1 and just say change this these pins, not very easy to understand

the instructions for series 1 are pretty much the same for 2/3 with one of the wires changing colour but all pin locations staying the same

The following wires need to be moved around, in order for the Mid/High Cluster to function correctly,
1. The Park Lamp Dial (+ Positive) Illumination needs to be moved from Pin 13 to Pin 2. - Brown
2. The Dial Negative Dimmer Illumination needs to be moved from Pin 21 to Pin 3. - Light Blue / Red
3. The ABS Warning Lamp Wire needs to be moved from Pin 8 to Pin 23 - Orange/Black
4. The R.H. Side Indicator wire needs to be moved from Pin 19 to Pin 26 - Green / Light Blue (Series 1 is White / Light Blue)

(Using the Photo Below) The Pin numbers start from bottom right and go in a U shape to the top right spread over the 2 connections, so a total of 28 pins one connection has 8 pins (that does not exist on base model wiring) and the other has 20 pins

this photos is of the back of a AU3 Fairmont Ghia Cluster with a AU3 Forte Wiring loom, with the pins removed from the connection
