obd2a to obd1 swap

ok so i had this guy put a d16y7 into my 94 civic dx so he converted it to obd1 and i have a idle problem a year later and it just gets worse. ive checked almost everything. now i want to make sure that the wiring is done right. the guy cut every wire and connected it to the wire in the ecu instead or using a jumper harness so now im trying to find the information to check it. if you can help feel free to reply. i have p06 running it if that helps
