does any one know where i can get a wireing diagram that will map out the process on converting my 91 crx si into the 95 civic si ecu. any help would be great.

 

just get the ecu pinouts from the service manuals at your dealership (or buy a helms) and determine how the jumper harness needs to be wired. it doesn't take a brain surgeon. it's not the easiest or funnest thing to do, but probably beats paying $150+ for someone else to sell you one that did the work themselves.

 

are u planning to replace with a z6 and use the z6 electronics and ecu? if so this may help. also if you didnt know, there are people who sell obd0-obd1 wiring harnesses if dont wanna do it urself or want to be able to go back to stock.
