the two ground wires ground out on the battery tray.

what year is your car and what year is that harness from?

I would say you are correct here.

Next the big black cable coming from battery+ where does this go, the starter?

[dirty thirty]

the car is an 86 and the harness is a 91 380 ecu

I would say you are correct here.

Were on the starter? The back?

The big wire for the starter goes where on it ?

[BavBeater85]

starter should have different sized studs, so youll be able to match by eye if you have the right ones running to it

[BavBeater85]

that sucks, my i motor came with the wiring harness till hooked up, even the starter was still on the engine and wired

Does any one have a pic of the starter installed in vehicle ?

Now i have the big black wire from battery pos on the wire wall and the red positive cable coming from the loom hooked up to the starter soleniod. there is a blck ground wirte that runs in the loom next tot the small red starter wire. where does this black ground cable connect to on the starter?

Far as i know the only wires that goto the starter power and ground wise connect directly to the solenoid and the ground mounts directly to the frame or block whichevers easier

Do bolth of these go on the two post on the starter soleniod.

[Bretts85E30]

That would be my best guess there are 2 posts on my early eta starter but i only have the shrouded wire on the left that connects to the solenoid on the top
