I bought them from ebay from gaugewireandcable (https://www.ebay.com/itm/132076737409). They are very well built and the wire is great quality. I used #2 AWG and replaced the battery to disconnect switch cable as well as the disconnect switch to winch cable.Very clean!
Where did you source the cables, or did you make all that from different parts?
I almost started buying terminal crimpers and what not, but found a short cable and just bought it. Custom would’ve fit better though
