But many E32 also, depending on the electronic wizzards which were originally ordered. If you ordered a phone or parked heating in those days, most probably the second battery was also needed.
Highline even have a second alternator.
This shows you the relais in the trunk, battery is not installed there but you can see the brackets. Always installed on the right side in trunk.

The small battery has 25 aH originally.
And yes, the online wiring diagrams show you all the wires and relais you have to install, if you want a second battery. Actually no need.

E32 750iL 11/88, E32 750iL Highline 03/90
