I don’t know how some others feel about it . But when installing any wiring on my vehicles I want copper wire Seems more and more They are selling copper clad aluminum stranded wire without Telling you . Maybe it works ok for some stuff I don’t know . But you might want to check next time you buy wire . Cut it scrape strand and see if silver Color shows up If so it’s copper clad . I’m sure most guys know this But just in case someone new to Building or restoring a vehicle Might could use this information . Any other opinions welcome I know there are guys out there who Know a lot more than I do .
