I had a B18a1 swapped into my CRX. I now notice that there is a plug and a connector that I have no idea where they go. The green connector is on the back of the block. The off white plug is coming form the same wiring of the alternator wires. I have pictures but i don't know how to post them.
Thanks

Was your car DPFI? Sounds like spare wiring to me if you ain't throwing any CEL and the engine/car runs good.

It's an '90 Si. The car runs good. The ECU is throwing a code 9.

code 9 is a cylinder position sensor.. ive been out of the game for a while but im pretty sure thats in the distributor...

there was a sensor on the back of the si intake manifold that as far as i concerned did nothing. if you unplugs it it didnt run any differently or threw a code. that should be your clear colored connector... the ls motor doesnt have that sensor i do believe.

as far as the green one take a picture load it onto a host site and post the link..
