I have a ef sedan but it has no cabin harness but I have one from si hatch can I use that so it would be mpfi or is that not a option?? I have a swap to put in it but this is my only setback

 

if your a wiz at wirring and pinning it can be done but it is a beach and a half best thing to do is to just do the mpfi swap in a dpfi cabin harness...its very easy... finding one could be a different story... i am currently parting out my sedan parts car if your interested in the cabin harness ill sell it for 20 bucks and you pay for shipping im in nc 28752

 

Is the sedan mpfi

 

cabin harness has nothing to do with mfpi. at all. lol

you need to change some wires on the ecu and that is it.

 

So why cant I use the one from the si

 

ok i got one to top you. i have a 89 civi SI i crashed. kept the car and baught a 1990 LX with the insurance money. the b15b2 in it is trash. so i am going to dumb my D16a6 in it. now my question is do i use the si harness and plug and play since i have the dizzy and ecu or is there still wiring that needs to be done. i have every part from the civic SI i just dont wanna have to wire **** if i can just plug and play. i looked this up for the last 3 weeks and i havent found a solid answer. help?

 

what exactly does your ecu plug into sir .. that would be the cabin harness therefore if you were able to put a mpfi cabin harness in a dpfi car there would be no wires to run to the ecu... wich can be done like i said but it is not plug and play...please correct me if im wrong and it can be proven im always up for learning new things...

 

no the sedan was a original dpfi automatic car i converted to mpfi and 5 speed so the mpfi conversion wires are still there but they would need to be ran to the appropriate injectors/ plugs in order for it to be mpfi.

 

as far as i know the mpfi si harness is not plug and play in the cabin nor in the engine bay additional wirring would still need to be done either way...

and yes i have tried this before the plug on the driver side that runs the fuel pump and i believe the tailights is different. and would need to be spliced from the donor car to the one you are putting the cabin harness in. im pretty sure the pins are different sizes.. so its really just easier to do the mpfi swap to the original dpfi harness..

 

so simply just keep the original LX engine harness and to the MPFI wiring to it and use the si ECU with the SI complete engine. im leaving the LX tranny since its a 5 speed and better on Fuel since this is going to be my DD. so literally there is no point in using the SI engine harness.
just the dizzy/ecu/engine w/intake mani.

 

right but you will need injector plugs off of the si harness for your mpfi swap and its always good to have parts harnesses... unless you plan on using obd2 injectors to rid yourself of a resistor box. then you will need obd2 injector plugs...

 

So my si hatch harness wont work in my sedan cuz from the driver side dood it has no wires

 

Still got the. Cabin harness

 

Txt me I have a few question 2148533511 but im a serious buyer for sure

 

Can I get that harness
