I haven't seen a wiring diagram that post the connectors and pinouts, just the typical wiring schematic. I went ahead and purchased this from ebay and manually scanned the pages. Some pages are a bit crooked or faded but overall still readable. I posted my one drive link here as the pdf is ~6mb while the upload limit is ~5mb.

Also...does anybody know how to de-pin the ecu connector? I can't seem to figure it out.
