Eberspacher D3WZ

[@joanmanentferrer8606]

Hi, I need help and I don't know how to fix it, I can't start the hidronic. I have a D3WZ, without a control screen, only wiring with a connector with cables 1,2,3,4,5,6,7. He connected: 1 to + battery positive 2 a - battery negative 3 cordless hay 4 a - negative to diesel pump 5th I think it's diagnostic and I don't know where it goes. 6 I don't know where it goes 7 I have counted it to positive pump and positive battery I don't know where I have to connect the positive of the pump because there is no cable in the connector that comes out of the hidronic, right now I have it connected directly to the positive. As data, the hydronic comes from a Saab 93 diesel and perhaps this is where the problem comes from. The hydronic does not start, can you help me please, I am a little bit 😩

ahha.. and what if mine threw sparks when I gave + to the sensor lead? :D grounded one lead from the pump and the big brown ground, all other went on +.. it sparked , and got the cables burned.. fan turns by hand good enough, pump clicks when i gave it direct 12V ... what was wrong ?

pump must be conected fully to webasto conector. No outer conections are going in too pump you only give plus and minus to webasto control unit and plus to two more wires from outer temp sensor and engine generator plus signal.
