If a solenoid only has one small contact and two large then it gets it ground, for the electromagnet, through the mounting bolts.
If it has 2 small contacts then feed + and - to them however is cleanest to your install, or flip a coin..
Direction on the 2 larger terminals with the battery cables, only matters with diode based isolators.
Which circuit did you tap? Does the solenoid click when the starter is engaged and again once you let the key spring back, assuming your switch is on.
Is your switch illuminated? its light can take the place of listening for clicks when cranking the engine.
A voltmeter on house batteries, if they were contributing to starter motor current, would drop at least half a volt during engine cranking.
