I'd bet that if we look in the 72 shop manual, it will tell ya

Here's a 71 manual, but it's "body only" no engine, electrical, etc

Well, heh, didn't see it in the 72 manual, so I checked the 70 manual from MyMopar

Page 672. (This manual does not use the proper "dash" numbering)

Does this look like yours?
