To the OP, note that you will still need a flyback diode to protect the switch, even if you skip the ext contactor.

I am familiar with putting diodes on the battery master solenoid. If I decide to only use the internal solenoid on the Skytec 149-NL starter, where would I put the diode?

Also, I am picking up the internal solenoid will draw about 5 on the activation line??? This seems high as I thought the battery masters only had a draw of about 1 amp (I may be confusing transient current flow vs steady state?) Please keep the advice coming, I am limited on my EE skills.

Ideally the diode should be as close to the master solenoid as possible. In this case that's not practical so installing it on the switch will work fine.
