5.3 into a 1990 OBS with a 5 speed

[99kon]

Red=always hot on the big nut of the starter
Purple=hot when starting on the small nut of the starter
(info based on my 94)

Mine is a 90
Should be the same. I wish I had a wiring schematic of the ignition.
If you see on both pics you'll see I bought new 2 gauge battery to starter wire and ground wire. Does the small black and red wire go with the purple wire on the small nut of the starter? Or does it go on the big nut?
