Hello people, I have the following concerns: My Omega B Kombi, year 97, 2.0 16V has a built-in AHK with a 13-pin socket. By measuring I found out that neither the continuous plus nor the so-called charging line (PIN 9 and 10) are occupied. Then I tracked the wire harness coming from the AHK socket and found that the wire harness appears in the mounting opening for rear left lighting. The wire harness has 13 wires. 10 of the wires are further bent. 3 of the wires end in a blind plug. At the AHK, however, I need the continuous increase for the 12V interior lighting of our caravan with the standing and connected tow vehicle as well as the charging line for the 12V operation of the Wwg refrigerator during the journey. Ideally, the charging line should be powerless similar to the radio as soon as the ignition key has been removed to unload the vehicle unintentionally. My questions: can you pick up the required power supply of the PINs 9 and 10 somewhere at the rear of the vehicle (perhaps even in the said mounting opening), or do you have to move separate lines from the front (battery, fuse box) to the rear? By the way, I am not a car electrician, so it would be nice to form answers as far as possible intelligibly. Thank you in advance.
