I am currently in the process if doing a b20 swap into my 1993 Del Sol Si. I am running a chipped p28. I need to know what engine harness I need. I have searched the internet for this information and I have found nothing solid. What engine harness will do the job?
Any information to point me in the right direction is greatly appreciated.

 

Are you running obd1 components?

 

yes.

 

obd1 engine harness from a civic or integra will work. Basicly used the engine harness that came with the shell.

 

If you've swapped over the OBD1 counterparts for the alternator, injectors and distributor it should be plug and play with your stock harness.

 

Im sorry, I may have made a mistake. I am still somewhat new to all this. Bare with a noob if at all possible... The swap I got is a 1999 B20B, that would mean that all the components would be OBD2 since it was from '99, right? My '93 Del Sol came stock OBD1? My p28 is OBD1? That what I have going on, I am pretty sure

 

OK, so your answer is get harnesses for from OBD1 to OBD2 or swap distrib, injector, and Alt as stated

 

Correct.

 

Thank you very much for your help, all you guys are awesome

 

You can reuse your Si injectors. Get a distributor from a 92-95 LS Integra and the alternator.

 

wouldn't an obd 2 integra LS harness be plug n play with the obd2 componets and obd1 car?

 

If that is so, that would be great because my friend is actually selling one.

 

It is possible as I just remember my cousin having an obd1 del sol with an obd2 engine harness. I suggest sticking with an obd2a integra harness. Please note that I said "OBD2A" and not just "OBD2".

 

Yes, I believe you could even use a 96-97 Del Sol engine harness as well.

 

Thank you, I will look into both of them!

 

How unreal, I am also doing a B20 swap into my 93 del sol and also had a question about which harness to use. The only difference is mine is a B20vtec, I am using a B16a2 head. I do not have a Dizzy, ECU, Injectors or Alternator yet. Can you guys please inform me the best route to go?

 

What del sol trim do you have?

 

Si

 

Which ecu? If you're using a P28 then you could just use a 96-97 Del Sol Si or 96-01 Integra GSR, or just use your harness with either adapters or OBD2 alternator and distributor for a Bseries VTEC.

 

obd2 LS into 92 cx

should be similar to your setup

I have an S that has been completely converted to an Si. Si harnesses were used throughout, even in the cabin. The engine setup is a B20B bottom end with a B16a2 head, relatively built engine if that matters. What would be the best OBD/harness route to go for? Again, I do not have a Dizzy, ECU, Injectors or Alternator yet, so I believe I am at free will to go any route suggested.

 

If you don't have those then go the route I suggested above

 

Got it. We'll I am going to weigh my options. I will let everyone know what I get after the swap to ensure it works. Thank you, everyone!

 

Just wanted to add this for the OP

From what I have read is that all 92-95 civics, all del sols and intergra have have essentially the same set of plugs from the shock tower to the ecu, you may not have all the wires though vtec etc ..., all 94-01 teg harness are the same at the shock tower end, whatis different is the actual plugs that are on the engine side for the sensors, fuel injectors alt etc, so you will want an obd 2 harness from a teg that has the engine side plugs match up to the engine, so if the sensors etc are obd2a or obd2b whatever that the kin of harness you want as they will all plug in at the shock towers

hope this helps

 

Perfect! Thank you!
