ok this is whats going on

i have a 98 civic dx and i'm swappin in a 93 b18a1, on all the post telling you how to do the wiring they say to use a ex 5sp harness but i was figured they only said that because they were swapping in vtec too, so i decided to save money use my stock dx harness

but im having a bunch of problems wiring this and cant afford a harness from rywire or anything so if anyone has some sort of diagram or any tips please let me know

What issues are you having? There are a few areas that need to be extended, but nothing major.

Ahhhh...see here inlies the problem my friend...unless your state allows you to run on OBD1 setup you are going to have plenty of issues with this swap. Your '93 engine is of course OBD1, but your car is OBD2. In order to make this run correctly (if it is even legal where you live) is to buy a jumper harness and use an OBD1 P75 or '92 - '93 integra ls ecu which is also OBD1 (PR4 I think). If not your ecu will be looking for things that your ls engine doesn't even have like a CFS, and a few other OBD2 only sensors. Tell us a little more about your ecu setup.

I was going to use a obd2 integra ecu

Then you are going to need a few extra sensors and you are right in using your dx harness.
