18 button OBC clock problem

[Lustiness]

Hello bimmers, last week I installed 18 button obc, everything works fine, but when turn off car, clock stops ticking... for example, time it's 16:35, I stop the car, go to shop, came back to car, time now it's 16:47, when start the car, clock shows 16:35 and start counting minutes. I found that, when car is off, when press Date or Hour button, nothing shows. No power to clock. I look at wires, but everything is good. When put 7 or 11 button obc, clock is working. I tried with another 18 button, same story, clock not work when car is off. I used schematic from google, not used for 1st time, already installed few 18 buttons obc on other cars, work with no problem... Can someone tell me where to search problem, witch wire to check..

Tell me what OBC your car had as standard and what changes you made

analog clock was factory, after that I install 7 button obc, last year I install 11 button with check control, everything work fine, now I install 18 button obc and I got this problem. I test it on other e36, work without problems...

Hmm I know you can go from 8 button to 18 by just moving the live and earth from the black connector to the whit connector and it works fine, then adding the other 5 IIRC wires gives you everything except gong, temp and code IIRC

So it was fin on the 11 button? Cool let me have a look at my notes

I don't know if this make something wrong in story, but I did not move +12 and ground from black to white connector, I just make bridge between both connectors, because I repair pixel on e36 OBC (7,8,11,18 button) and test em on car.
