99civicsi b16a2 into a del sol

Thanks for answering. I live in Ga and there are no emission tests or enforcement, maybe in atlanta. There is all kind of junk on the road here. Just so you would know I have both cars the del sol is a total that I am fixing and the 99si is the one with the motor but it is fire damanged. The ecu and part of the motor wiring is burnt, but I have a ecu form a 2000 si. Still no 99 civic wiring. I got the 99 cheap at a sale.($1000). Thats why I would like to use it. I have be told I could use the del sol wiring which is obd1. I guess what I want to know is if I took off all the wires of a jdm b16a and all the wires of a usdm b16a would they be the same if so it seems i could use my del sol wiring. That is i would be able to keep it obd1, i heard its a lot of trouble to change to obd2. Besides I would have to buy the correct wiring harness. Not that i wouldnt if thats best. What do you think. Again thank you.
