My Hirschmann Automatic Antenna 6000U 481 quit working so I purchased a replacement. The replacement has 3 wires Hot, Gnd, and one going to the radio.
I've tested all the connection coming from the car to the old antenna and the pinout is as follows
1 12VDC
2 Ground
3 Ground
4 Blank
5 Not sure
6 Not sure
Both 5 and 6 are black wires and I'm not sure what they are used for.

I'm wondering if any of you have replaced this antenna and how did you wire it?

See attached photos of old antenna
Thank for your input.

5 & 6 enable the positions up max down. The replacement is just up or down not 3 position like Hirschman. Just needs power. Will post wire diagram for Hirsxhman if you think you need it
