Went to buy plug wires and I was asked if I had the AC Delco or the Magnavox ingnition? I have a 92 Bonneville SSE n/a. Can anyone tell me a way to tell the difference?

At the front left of the engine, all the plug wires start on a module. If the module has three seperate "coil packs", it is AC Dleco, they look like they have a ridge on top and could be turned by hand, although they can't. If it is one piece, Magnavox.

This is AC Delco. If the tops were flat, it would be Magnavox. Ignore the scrunched look, it was after I rear ended someone.
