Can someone point me to the find ampacity tables for automotive wire? I'm looking at SXL in particular, SAE J1128. I see the wire has a temperature rating up to 125 C but I'd guess the terminations may be a limiting factor as with building wiring but I'm not finding much on it. Thanks for any assistance.
 
Is that a 125°C rise or ambient? I would think voltage loss would be unacceptable long before you reach temperature limits.
