For a 1970 Cutlass 'S' Holiday Coupe with a 350 2bbl V-8 engine (not a 442): which wiring diagram to choose from: 442 diagram or F-85/Cutlass diagram?
As I can tell, this has the body style of a 442 (so does an F-85) but without the high performance of the 442 but the F-85/Cutlass had only a 6 cylinder engine and I have an 8.
So I with the Holiday Coupe would choose the 442 wiring diagram? Is this correct?

Why spend money on just a wiring diagram? Buy a Factory Chassis Repair Manual and not only will it have the wiring diagram, it will have almost all the information needed to perform most any repair to your car.

^^^THIS.

And there is NO DIFFERENCE between the wiring diagrams for a Cutlass vs a 442, except for the alternator (internal regulator vs external).
