I'm swapping a SIR2 B16a into my 95 coupe. I've used the engine harness from the sohc engine. There is a 'loose' plug (square type, 4 leads) that leads towards the exhaust manifold.

On the exhaust manifold, the o2 plug leads towards the back of the block (square type, 4 leads....but the wire colors don't match.) Are these the correct connections?

The engine wiring harness from a 96 integra, the engine that I once had, has the o2 connection right where the o2 for the header connection is, which is why I'm confused.

TIA for the help yall!
 
You should have four wires and they should be...

GRN/WHT
WHT
ORG/BLK
YEL/BLK

Those are you o2, and the connection should be at the front of the motor with the stock harness.
 
Right on!...I forgot that on the sohc the o2 sensor plug was where you described. Looks like I'll be extending some wiring then. Thanks again!
