I recently swapped a jdm b20b into my integra which is obd0. I used my stock ecu and harness, i noticed that there is two plugs with no where to go hanging in the back of the head. The motor starts up fine and idles ok, hasnt been fully test driven yet. Am i going to run into any problems because of these 2 plugs or should it be fine? There is no CEL also

 

I got this one
I believe one of them is for a knock sensor/no worries-
Are the wires together?pics?
The other may be for your fan? did you run it for a lil bit and see if your fan came on? i had to modify mine for it to work, and it's in a 90 da chassis..
I've found it easiest just to wire it up to a switch

 

thanks man, i dont have pics yet but im sure it'll be fine, if anything i might wire my fan to stay on 24/7 just for cooling purposes

 

no prob hoped that helped..i been there btw, you're gonna LOVE that torque anything else lemme know
I would advise not to have the fan on 24/7 unless you plan on changing your
engine bays color to charcoal,lol..from what i've seen up to a switch with a 30amp inline fuse if perfect

 

yeah cant wait to see how it goes, i also put in a ys1 gsr transmission with a stage 1 exedy clutch and 8lb fidanza flywheel, removed my a/c, cruise control, and power steering. Should be fun haha

 

Gsr trans huh? ganxta! right on getting rid of all that useless weight sir
I sense a full wire tuck in your future,haha..been watchin' your progress since the beginning, good shyt there man is it just for street duty? or you got other plans....

 

well im probably just going to leave it like this for awhile, im expecting a kid in not too long, i'll probably go b20vtec once i get bored of the current power haha
