Can someone tell me just how hack my swap is?

[jealous1shateric]

You have an auto ecu hence the code 17

Holy hack job. whoever did the wireing in this car should be dragged into the street and shot. From what I can tell from the pictures 2point1 is correct with identifying the plugs and wires. Honestly I personally would start fresh with a new harness and ecu. And absolutely get that timing belt done asap before u smash those valves. If u dont want to buy another harness and have another car I would rip that harness out while doing the timing belt and fix what u can on the harness.

This ^^ is a mess of VTec wiring. The green/yellow wire without a plug goes to the VTec solenoid. There is all so a mess of distributor wiring under the tape.

Does that meant this this wire coming out if the harness is is supposed to be the one in the this plug?

[godesshunter]

If I start fresh with a new harness and ECU. Would it make more sense to get a harness form a 99 ex and ECU to match for this engine? It should work in my 93 chassis right?

No u want a 92-95 ex/si engine harness for the year car /make model engine

the only issue i see with the info that has been answered is ive never seen a eg body style that didnt have the map sensor on the throttle body i could see the reason the vtec wire isnt used from the actual harness being if the del sol was non v and the changed just the engine harness the body harness wouldnt have the vtec wire in it therefore ud have to run it that way or back wire to cannon plug

92-93 civic had the map sensor mounted to the firewall,the wiring is part of the cabin harnes not the engine harness.

Can anybody tell from the pics what engine harness I currently have?




If this realy is the map sensor plug for the firewall, And I have the throttle body mounted map sensor that is plugged in, ( you can see in the right side of this pic) then does it mean I have a different harness from OE 93 Del sol harness?


on another note.



This is definitely my crank sensor. I just did the timing belt last night and that is clearly what the plug goes to. How is the engine running with not crank sensor signal?

Thanks Ed. I may take you up on the offer once I figure out what is realy going on and what I'm going to do about it. I halfway considering ditching this whole swap and getting a bseries. Im trying not to spend alot of time and money though. This car was supposed to just be my easy daily. Its turning into a headache though.

The obd1 comp in a delsol doesn't look for a knock like a obd2 ecu would its not necessary if u need help I can help you I also have a vtec harness uncut

Obd1 ecu doesn't need or look for that crank sensor,so that plug doesn't need to be used with an obd1 ecu,will run fine with out it and not give a code. Obd1 all so doesn't look for a knock sensor.

The del sol uses the same harness as the 92-95 civic and 94-01 integra. The 92-95 civic harness doesn't have a crank sensor plug,so the harness didn't come from that or the 94-95 integra. Now the 96-01 integra does have a crank sensor plug but it's a 2 wire plug,So it's not an integra harness either. That leaves 96-97 del sol as that would have a crank sensor plug and should be 3 wire like the one in your pic. The only other harness that plug would be on is an auto harness or a gsr harness but the plug would be on the pass side with the rest of the shock tower plugs.

Wow! loads of great info. Thanks so much. Still not sure about the harness though.

The engine has that sensor on it. However it isn't plugged into the harness. From what I can tell, there is no female plug anywhere on the harness to plug it into if I wanted to. So... Its possible that its the original del sol harness. Maybe...

In theory, would all the other plugs on the 93 del sol engine harness mate up properly with the 99 D16Y8 engine?

Then there is the question about map sensor... Why would my harness have provisions for both styles of map sensor? The engine has the throttle body mounted map sensor. And its plugged into the harness.
Coming out of the harness is also a plug (as described above if correct) for firewall mounted style map sensor. But it is not plugged into anything. Is it normal that my harness has both style plugs and only uses the one that is appropriate for the map sensor being used?

[godesshunter]

And about the Vtec wire. In doing more research I read that the 92 and 93 Del Sol harness is pre-wired for Vtec even though it wasn't used. for those models. If that is true, Is it possible that this wire coming out of my harness is precisely that?

[2point1]

You have two map sensor plugs cause in 92-93 the map sensor was mounted on the firewall like the 89-91 civic. Honda move the map sensor to the top of throttle body in 94. 92-93 map sensor wiring is part of the cabin harness not the engine harness. 94 the map sensor wiring is part of the engine harness. The engine harness that's on yor car is from a 94 to 97. I'm not 100% sure if the wiring is in the shock tower plugs for the map plug on the engine harness to work. So just use the one that not on the engine harness.

For the VTec question. It should be wired from the factory but not all of them are. That is a VTec engine harness. The green/yellow wire without a plug on it is for the VTec solenoid. At some point some one ran there own wires from the ecu plugs to the VTec on the motor and that's why that green/yellow wire is like that.

From your pics it all so looks like the distributor plugs where swapped from obd2 to obd1.
