hey, i got a honda civic dx and i put a b18 a1 in it (integra engine) what would be the best wireing harness to use its very frustrating.
thanks

The best thing to do is use the harness that came with the civic and either send it out and get it modified for the b18a1 or see if you can get a hold of an si harness, those harnesses are plug and play with the b18, thats what i did.

 

Just add mpfi to the stock dx harness. Might take an hour?

 

ok, so im in the same boat with him. im gettin my motor built and boosted and i was wondering the same thing. i already did a mpfi swap with my d15b2 that i currently have. so therefore all i have to do is plug up the harness to the b18a1 right. and of course get a working chipped ecu made for boost and plug it in. thats all right.

 

Yep, just plug it on up.

 

cool, just saved myself a buch of money by switching to b series!!!
dunno why i had to say that but thanks. ya did sorta save me, before i went and bough crap i didnt need like a extra wire harness

 

i got a si harness in today so everything will match up with it? like i dont have to chop it up or anything?
thanks for ur help

 

nope, plug and go

 

the Si MPFI engine harness <U>will</U> <U>not</U> work with your DPFI DX - you need to use the DX harness and do the DPFI to MPFI wiring changes (or send it to Rywire and have them do it)

 

^ for sure don't even try it!!!

 

hey i came across a problem, the whole wireing harness is all pluged up besides the ecu conector and the ignition one too what can i do to solve this problem cuz i'm 2 wires away till i can drive it!!!!
thanks

you CANNOT use the Si harness.You need to just use your DX harness and change it over to mpfi.So just pull the Si harness back out and put the DX back in and modify it to mpfi.

 

theres no way i can? like not possible? everything matches up but 2 things its like a 50/50 thing like half of the people i asked says SI harness and the other says DX harness and both seemed to work for everyone
i cant convert the si harness to MPFI?

This means that half of the people you asked are asshats!

You can use the Si harness if you use the interior harness also.....it's going to be a HUGE headache.

 

lol the used harness meaning the ecu harness too? cuz i dont have that lol dammit! people put me in the wrong dirrection now i wasted alot of money owell thanks for the help
