hey so picked up a 91 civic si with a jdm b16a swap, obdo still with a pr3 ecu. i dont know how to get a hold of the owner before me so im trying to figure out what they did to the harness. i've pulled it all into my cabin and im prepping it for a full wire tuck but there's a few wires that came disconnected so im trying to fix the whole harness and make sure its done right but i need to know what harness they used. im thinking they used the originally harness from the car, which is an si, and then modified a couple wires but i just want to make sure so any input would be appreciated.

 

So I'm confused....You want us to tell you what harness someone else used when 1 we don't know who did it, 2 we have no pictures, and three pictures would likely do no good since you already pulled it through the firewall.......................................... ............
I think that the only answer that we can offer you would be NO....

 

Well, unless they used an entire Chassis harness from the donor vehicle, there's a pretty good friggen chance they just used the stock harness and added any extra plugs/wires needed
