so i am in the process of swaping the b18a1 from a 90 integra into my 91 dx hatch. Has anyone done this, or a similar swap? If so how did you modify the wiring harness or, what harness did you use i was tempted to just modify the existing civic harness, but i feel that my be more difficult than modifying the integra harness... otherwise tomorrow i am going to the library and getting the diagrams for both cars and just splicing the integra harness into the civic well wish me luck and thx in advance

You have to convert the dx harness to mpfi..
You dont have to worry about the obd since 90-91 integra is obd0 and you're car is obd0 also..

If you cant do it then you have someone make a harness for you..

"Blown90hatch" makes them..
"Droppedcrxsi" makes them..
And many others..

Or you could go to hasport.com

 

if you want wiring diagrams, just use the search option in this forum. just type in mpfi wiring (multi point fuel injection) and you should get plenty of pages of people who have done the swap before. good luck with your swap.
