i have an lsv that i built. appears to be a head from 99-00 si. however came with an obd1 intake mani injectors and rail. I swapped the injectors and is ok however there is an extra plug in the middle of injector harness. Not sure what its for? can i even use this intake manifold/throttle body and fuel rail set up on my obd2 set up?

 

can it be converted or should i try to use the obd2 ls intake???????

 

Year/make/model of car? What engine harness are you using? Sounds like its the Evap Purge connector. Is it black and two wires?

 

its a 98 ex civic formerly a sohc vtec d16y8 with the factory harness. i know its a 2 wire connector as far as the piece it was attached to the fuel rail on the y8 but the new b16 mani fuel rail doesnt have it.
