JDM B16A1 wiring/distributor ?'s

Ok i swapped a JDM b16a1 into my 1991 civic dx. I am using a 88-91 crx si wiring harness and the plugs dont match up with the distributor the plugs on the distributor which the part number says is a td22-u. The plugs for the distributor are a big round one and a squarish one. What do i need to fix the problem new wiring harness or new distributor or what?

what did u do with the factory wiring harness

ok first off, if you have a 91 dx, you use the 91 dx engine harness and modify it. if you plug in a si engine harness to a dx chassis harness, it wont work. and its not that hard to figure out you just need to change plugs, but also if you are using a si harness the dist plug should be a round one, and the b16 is a round plug too. only the dx is a square dist plug
