Seat heat lupo

[gacsger]

 

Hi!

 

My Lupo has already have ‘half’ seat heat system. I mean the loom, relay, and switches but the seats do have not any heater things. So I have bought after-market heat panels but it has just two wires. Positive and negative. (red, black). The loom cabel hasn’t got any connector under the seat. It has four wires (without connector) Black, brown (these are big), and yellow, red-yellow. I have measured the voltages but one of them has no voltage. (I think it is the ground). 

 

So my question is,

 Is it possible to connect the after-market heat panel to the loom? 

And what kind of wires are there under the seat? (positive, negative, etc.)

 

I would appreciate your answer guys thanks.
