i just put a b18a into a 90 civic dx. i have a si cabin harness and also si engine harness. there is a plug from the si engine harness that i don't know where it goes. its is 2 wires, blue and black with yellow stripe (its supposed to be behind block or around there). can anyone tell me where this plug goes. also there is a green plug on the b18a block, i believe it is the secondary temp switch (saw from previous posts), does that need to be connected. i havent got a ecu yet but i am putting a 90-91 ls ( same for the motor) and was just wondering if those things need to be hooked up so they won't throw any codes. any info greatly apreciated

thanks

thanks</TD></TR></TABLE> HA HA I'm trying to find out the same thing on that 1st plug.
this one right? anyone that knows please tell us!!!!!

 

yeah thats the plug. are you using a 90-91 obd0 ecu too. did you wire up that green plug behind the block. if so can you tell me where it goes or does it throw a code. i thinking the wires might go to the purge valves next to the map sensor. is it giving you a code for not having it plugged up??

 

switcht he plugs around you might have them mismatched somewhere
