Wiring help. Links appreciated

I have been at the edge of insanity trying to figure out the wiring on my wagon. I bought the car and it was already mpfi. Swapped out the old motor and sold everything(dumbest idea ever) Installed the B18 and the harness didn't work. Tried another harness and it was sending signals the wrong way. My question is, does anyone have it written down on which wires go to what? I made a little diagram of my 3 main plugs coming out of the firewall and want to be sure that they weren't tampered with previously so I can match up the engine harness to each individual plug and get my Jefee going. This sounds like a long shot but can anyone out there check their 3 main plugs, coming out of the firewall, and write down the color wires for each plug? It took me 10 minutes to do it on my wagon and I need the wire colors for the two round plugs and the rectangular one on the passenger side. If not than can someone/anyone send me a link that has everything. Also, my wagon is still OBD0 and converted to mpfi already. Thanks and sorry if I'm being a pain in the A**.

I accidently sold the original harness and didn't realize what I had done til couple days later. The thing is, I will not wire up another dual point til I figure out if the 3 main plugs have been "modified" or repinned. I tried a dpfi converted to mpfi and it didn't work. I just need a link or something to see if all my wires are stock or have been changed/repinned to different locations on the plug.

I'm gonna see if I still have my diagrams I made a few years ago - I think I did the colors and locations for each wire on each plug - hopefully I still have the notebook. I'll look in a few.

Thank you. I matched up the 3 main plugs on the car and than on the dpfi harness. All wire colors are the same except for two wires on the passenger side round plug. Pin 3 is white but is connected to a larger brown wire and pin 9 is blue on the firewall plug but yellow on the engine harness. This is why I would like to get ahold of a link or something. Thanks people, really appreciated.

No luck on my notebook yet - I'm still looking though.

Whenever you can. Thanks.

I went through all this (Tried to run DA Integra OBD0 loom) and the easiest way I found to fix it was get another shuttle loom and just modify it to work with the new motor.

By easiest I mean I got it running but it looked ugly as I had to run jumpers from the right to the left side since the locations of where wires enter the car was slightly different

Ya, I never thought of rywire, he might even have some he could send you.

Problem solved! I went to the junkyard and checked 5 other cars(1wagon, 1 crx, 2 sedans and 1 hatch) All my wires are the same as these other cars. Even the blue to yellow wire that I was worried about. Thanks guys been really helpful and I greatly appreciate it.

So, do you just have to re-pin your harness now??? And hopefully fire up your wagon??

JDMWago666

From the looks of it, yeah. I want to convert the dpfi to mpfi just to be safe cuz I still do not feel comfortable with the other harness.
