Which ECU?!?!

[Boostin510]

I have a s14 with a redtop sr20det. I have a sr wire harnness for a blacktop sr converted for a s14. Which ecu do i need to get?

Depends on what black top it is. If its an early S13 blacktop harness/engine, you can use the redtop ECU.

I have the ecu for the redtop i believe the number is 63 but the harrness plug dosn't fit into the ecu.

You've got a redtop motor blacktop harness and redtop ECU? I don't see why the ECU plug wouldn't fit, maybe you didn't bolt it down? Unless maybe you have a harness for a S14 SR VTC motor? I'm not sure if the ECU plugs are different between the two. Where did you get your harness?
