a little wiring help

[dabuilding]

ok so im doing a b16a2 in my 91 dx sedan and the motor was in a 90 si and he gave me his wiring harness but i have a problem on the drivers side the connection coming from the injectors is differant from the wiring that was in my car how can i make these match up please help me reps will be given i also have pics to clear it up
this is my clip from the firewall with 12 connections

this is the one from the b16 it has 8 connections but it has a green plug coming off of it with 5 or 6 connections

also this connection here is on the drivers side and has nothing to go to does anybody know where its supposed to go

sorry for the crappy pics its the only camera i have

if the harness he gave you is the stock b16a2 engine harness from a 99-00 si then you will need an obd2 body wiring harness...or get the plugs and figure out the pins

i am not sure, dont know too much about wiring.

From seeing your other thread about the swap, you had DPFI before this. The problem is that your new eng harness is MPFI and the chassis is still DPFI. What youll need to do is install your DX harness on the B16 and do a DPFI to MPFI conversion. The connectors are diff between the Si and the Dx harnesses and just dont plug in.
BTW, the green connector is for the injector resistor box.

Here is a decent write up on the swap. DX to SI swap

thanks man yea it was dpfi i forgot to mention that and the harness came from a 90 si
o and busdriver is there any way i can do it without running new wires from the ecu can i just use the existing clip man

Honestly man, I couldnt tell you. Ive never done the conversion before but I plan on it eventually on one of my hatches ((i have too many cars.....)) Ive only glanced through the conversion a couple times and never got in depth with the reading. Its just one of the billion things I pointlessly research.
Good luck with it though. If anything, hop on Honda-Tech or EF-honda or CRXCommunity, Im sure there are tons of threads on those sites about the swap.

it is such a pain in the ass searching forums lol but im pretty sure i got it now im just running new wires in a few places the only thing i need is for my buddy to bring me my damn resistor box
reps for the help guys...if i can
believe it or not the diagram was what i needed i just had to copy it down onto paper to understand it and now i think i got it

[Bus Driver J]

Awesome man, I hope it works out for you. You can send a PM if you get real confused. I have the complete EF wiring diagram on my laptop and Ill look something up for you if needed.

when i did it before i used the resistor box and just used the dual point plug wires for 2 certain injectors, ran all the grounds to the resistor box, and 2 power leads from the 2 new injectors to the ecu its self. i think, its been 5 years ago,lol.

[dabuilding]

yea thats how to do it i got it now
