Follow this link to access BMWs WDM. This has the wiring for ever model BMW produces. You need to have Java installed and go to Adobe and download + install SVG viewer first. then you can look through the available variations of models (US models don't have DRLs), so look up a US model with No DRLs and you'll have your wiring diagram. I also have the WDM on CD too if you need it.
He seems to have dropped the e36 and e30 from the online version, so you may need the CD. I live in Brampton, anyone who needs the WDM CD (or BMW TIS), let me know.
