Wiring Schematic Numbers and Labels

AllData does not provide any wiring schematic legends to interpret the symbols or numbers.

I am reading the Power Distribution from AllData. There is no help/guidance to interpret what the numbers refer to such as "EBD60" for KIA Soul in their Power Distribution wiring schematic. Attach is a screenshot example.

Where do we go to look up what the numbers and labels mean. I get the wiring color, but 0.3 BR means Brown wire, but what does the "0.3" refers to on the wiring schematic?

Thanks in advance.

Took a look and found this reference called out on this website: www.auto-facts.org/automotive-wiring-diagrams/

Attached is a snip from the site showing this reference

Hope this helps

Those n.n numbers are the cross sectional area of the wire in square millimeters. Basically the metric equivalent of AWG and backwards to AWG. Bigger numbers are heavier wires in metrique. Kinda helps to know whether you're looking for a skinny wire or a fat one. Other than that ignore it unless you need to bypass a section of harness.

FWIW the OEMs do include a how to read wiring diagrams section in their SI. I don't know whether that will be available in AllData???

Yes, thank you so much. I hope this helps other newbies to the new vehicle wiring schematic. I am old school from Chilton's/Haynes Manual.

I had to search the meaning of "FWIW"--LOL. No, AllData does not provide much details that I could see in terms of wiring schematic legends. As for Original Equipment Manufacture (OEM) maybe it will provide the details about that specific product, but I do not think that much information will be provided on all vehicles in AllData. I watched several YouTube videos where some content creator would provide some information on what they are working on. I guess they have the business account to be able to view multiple cars/trucks. I can only view one automobile per subscription per year. It is expensive for DIY mechanic at home on his/her automobile.

Thanks for sharing1
