Im hoping someone can help me out.
I recently acquired a dash pod gauge, and following Lennys guide, want to fit it to my TDCi. I want to keep the original gauges and drive them of the canbus. My problem is that there are alot more pins than I expected. I think I have worked out that all the pins I want are on the same row, and I think the order is as follows
1. Can H (?)
2. Can L (?)
3. Think Power + (maybe dial illumination)
5. Power + (IGN)
6. Power + (Perm)
On the other row appear to be at least two pairs of DATA lines and another GND.
I have applied power to 4 and 6, then jumped 6 and 5. This cause the gauge to zero, pulling about 90ma dropping to about 35ma a few seconds later.
I know the middle boost gauge only reads to 1.2 bar, and on a diesel you will need 2 bar for full boost, but the gauge actual has a sweep of about 345 deg (almost one complete cirlce. So if I just offset the needle to be horizontal pointing to the right, then two bar would be approximately horizontal to the left. Anyhow, getting into irrelevant detail until I can work out for definate which pins to use. So on with my plea for help:
Can any body offer a wiring diagram, take a picture of the actual plug (fitted in RS and ST I believe), or attempt to decode the colours and location of the attached picture (You wouldn't believe how long it took me to find this!)
