Power FC Issues Early Black top or later gen?

I’m Having some problems deciding what type of Power FC i should buy, because when i got the engine it came with an ECU I dont remember what ECU because the ECU was stolen from me last year when I took it off to send to enthalpy for a tune along with my Toyota 4Runner.

So my questions are :

Do I buy a red top PFC I found at a great deal " used "?

will the commander work with the engine I have if its for a red top and I buy a red top PFC ?

I’m also doing a wire tuck but without cutting too many things, I’m extending the headlights/flashers/ CAS/ MAF/ a few other things but soldering them properly and heat shrinking etc…

Do I have an Early Black Top SR20 Engine or later gen 1996.5 and up?

Any other possible things that can cause the problems… ?

I got the VIN # from the front clip my motor came from : HEre are details.

TYPE : E-RPS13

Chasis # : RPS13-323048

Model : RPS13JFTG50

Color Trim : 32b G

Engine : SR20 (DET ) 1998 cc

Trans Axle : FS5W71C RC40

Plant : X
