Electrical Wire for nozzle spray r129

[R129mine]

Hi

I cleaned up the spray nozzles and discovered that none of the wires connected to the nozzle were plugged in (now rectified)

I understand that the wires are for the heating element inside the nozzles.

I also found these 2 dangling from each spray nozzle. I am not sure what they are for and how they should be wired up. There is no wire between the left and right hand side spray nozzle

Anyone know what they are for. Found this diagram but it is not entirely clear to me. There are no loose wires in the bonnet left

Had another look

I don’t have a heater wire in the pipes. You are supposed to hook them up to the heater element in the wire but you don’t have one I guess you just have to tuck it away

The pipes are joint up in the middle of the bonnet instead on the side as per the drawing.

Anyway don’t drive it much in the winter now anyway to avoid rust etc so non issue.

Likely to be similar to this- WITHOUT the heated lines just the injectors.

circuit is pretty simply via a thermo switch
