Here is a better photo of the asset tracking QR code on my unit. Reading my code it is EE-00000019671000397230120270. Skydance's code is EE-00000019671000397223410579. I was assuming the EE-0000001967 (human readable) was the part number and the numbers after that were the unique serial number of the specific unit for tracability.The Part Number PA66-GF15 is a relay - would this be a relay for the lights and also towbar electrics?
