Which ECU!?!?!

[Boostin510]

i bought a wire harness for a s13 blacktop sr20det to fit in a s14. The ecu connector on the wiring harness does not match up to my ecu for my s13 redtop sr20 that i'm swapping into my s14. ( the ecu number is 63) So does this mean i need another ecu or do i have the wrong wiring harness. If its the wrong ecu which ecu should i get?
Thanks-NICK

sorry, you have the wrong harness... If you're choosing plug and play.
Just get the right harness.
