I have an Integral LS engine harness and I need to plug into my '91 Si. I didn't notice that the plugs were different. So now I have the right plugs but need to know which pin goes where. I searched for a diagram but couldn't find one. So please let me know if you have any suggestions. Thanks in advance.

Oh and I have a obd0 B16.

 

HELP

 

what happened to your '91 si harness? the only replacement harness that matches is the 91 si harness. I am not aware of a conversion diagram anywhere, but why do you want to swap it out? the 91 SI harness does everything the integra one does for a swap.. so there really is no point..

 

It was acting up after a wire tuck. The only reason I swapped it for a DA harness was because I wasnt able to find a Si harness. Everything on the motor plugs in fine on my B16 but 3 plugs dont plug in on my cabin harness. And its already heat shrinked and it looks good so I really dont want to swap it again.

 

I found the wiring schematic for the Si but not for the DA

 

Did this ever work by chance.?

 

probably not. because the DA and the EF chassis have completely different harnesses. no way in hell the shock tower plugs are the same. EF has 1 plug on driver (not includeing resistor box) and DA has 2 (not including resistor box) and passenger side are 2 rectangular plugs and 1 round for EF (si model) and the DA has 2 big round plugs and a 3rd 2 pin plug.

better off waiting for the correct harness, fixing original or buying a new replacement harness.

 

Yeah I'm actually in the middle of a complete harness build for my 91 ef I'm using my hold one witch was cut in a theft and melting for who knows how long. But I am using obd0 ls harness and my old one to build a complete new one. Between dpfi cause I'm in the middle of this as we speak, the bodys so front door jams back.they are completly diffrent even down to most connectors. As far as to the bay. Yes there are one or two more on integra, not sure off top I could go look but I believe there are two signals from ecu that don't exist on civic, dx, both harness are 91' tho doffrent they mostly run all on same circit. I'm on fuse #10 now and it's been the same so far
