Previously before taking anything apart I tried jiggling the turn signal while the reader was trying to connect it did not seem to do any good. I left the panel underneath the steering wheel off there is a green wire that connects the turn signal that is disconnected if I can figure out where to solder that back on that should at least fix my dashboard issue... I read another post that you attach the green wire to pin 3 to fix the dashboard issue but I'm not sure where pin 3 is!

Oddly I don't it must have not had very much solder on it to begin with... I can't find my wire strippers so I'm about to go to the store pick up a pair strip the green wire back connect it to the one I think it is and maybe my problems will be fixed. Will post back soon!

All the ones I can see from the bottom have wires, so if one is missing a wire, I am sure that is it.

Does the green one have it's own pin or is it connected next to another color? Because I cannot find it at all maybe I have to take the steering wheel off to get to it.

See the green and pink wire at the bottom? It should be a lug just to right (toward passenger side) and slightly above it. Sorry, the quarters are too close to get a good picture. It is not shared with any other wire.

Thats not the green wire that is detached the one that is connected to the turn signal is detached. See picture IMAG0333.jpg.
I attached the green wire that was detached and my console lights came back on steady but the left half of my dashboard and the headlamp indicator that tells you your headlights are on are completely out now. See picture IMAG0335.jpg. Theres not a fuse for this is there?
On another note the OBD II still wont read so I'm guessing it has nothing to do with this...

I'm not the best with electrical, I have an ohm ac dc meter but what setting would I place this on to check the voltage at the fuse?
Thanks

I did check the fuses for continuity with the multimeter and they are good.

BIG UPDATE ... this is where I'm at on this problem
Ended up taking it to the independent mechanic to have all the wiring checked it was there for a few weeks everything seemed good they cleaned up a few grounds but nothing major. I had an airbag light on so we replaced the airbag module underneath the passenger glove box and that light went off. The independent mechanic said he thought it needed to be reflashed he had heard of these Denso ECU's losing there flash. He didn't have the equipment to reflash the ECU so I had to take it to Jaguar...
Jaguar told me I had a bad ECU and would have to replace it. AND IT WOULD COST $6000 to replace yes that's right three 0's!!!! Does anybody know anything about this? It seems odd to me that the vehicle still runs with a bad ECU. Yes the check engine light is on but I'm pretty sure that's related to a misfire in the engine not a bad ECU.
What do you think guys, just a Jag dealer trying to scam a large amount of money? Or do I really need an ECU to be able to read my OBD II again?

Hi guys, just another question, maybe there is a solution to this that is making me crazy.
I installed just for experiment a volo vp12 chip on my car.
The chip requires to get full performance a period of 120miles driving, and i was the most sceptic of this world but i have to say that works, the performance improvement is evident.
But there is a big big problem on XK8 and i think also other Jags.
The car after 10-15 minutes cut all the +12v to all the car except the integrated alarm.
So ? So here is the problem... Everytime i switch on the car the chip need to recalibrate and i cant move the car for almost 2 minutes until it finishes, and the worst thing is that without that about 100 miles driving the chip does nothing because he must achive car data, and he loose all memory everytime...
Is not about to trash the chip, 129 bucks are not a lot, but im really angry because that little toy really works, i dont know how and why, but it works...
I just need to understand if is possible to dont let him loose the memory everytime, even because i cant be stopped 2 minutes everytime waiting for his calibration and not almost never (except today for trying it) i drive for so long no stop.
The chip is connected via can pins and +12v pin 16 and ground 4
Any help is appreciated![Wink](https://www.jaguarforums.com/forum/images/smilies/wink.gif)

The problem is probably related to the vehicle's CAN bus going to sleep after 10-15 minutes in order to save battery power while the car is off. Although it might be possible to devise a way to defeat this, then you will have a load of probably around half an amp constantly on the battery when the car is parked. This will drain the battery in a couple of days or so, therefore it is not a good solution.
Sorry I do not have a better answer for you.
