Getting My Starter Back Wired (Hot-start Relay Edition)

[OsoMoore]

Engine is almost ready to start up after rebuild, but scratching my head about the starter setup.

New wiring harness has 3 wires:
Big Red, Yellow 15a, Yellow 50

From the car body right nearby:
Big black

From my hotstart relay kit:
Blue connector (gets one of the yellows)
Small Black
Ground

My solenoid has:
Big bolt on left (ground?)
Spade on bottom (horizontal)
Spade on top (vertical)

I'm not sure exactly where they all go. Here's my best guess so far.

Yellow 50 -> Blue receiver
Yellow 15a-> Bottom spade
Small Black -> Top spade
All Three Grounds -> Big bolt

Something doesn't feel right about that - is the red from the engine wiring harness actually positive and should go elsewhere?

The big red coming off the alternator goes to the black wire, which is coming from the battery. They hook on a large terminal.
The solid wire yellow goes to the top tag yellow wire with the blue stripe goes to the bottom tag.

All good, thanks Bruce.
