Hey all, I'm confused and need some help please on what to order. I bought a 2003 Yamaha 90hp (90TLRB) that didn't come with the wiring, gauges, or the controls so I'm hoping someone can provide guidance so I can order all at once. I'm looking at this rigging guide but it doesn't list the year besides 2005 trim and oil harness. https://cdnmedia.endeavorsuite.com/i...ging_Guide.pdf
I bought a remote control with 10 pin plug going to engine. I plan on only using a tachometer and fuel gauge on dash, and speedo and voltage I'll get from Simrad GO7, and trim level I'll just turn my head and look. What parts would I need and what would remain unplugged on the engine (if anything)?
Analog tach: 6Y7-83540-90-00
Dual fuse harness: 6Y5-83553-N0-00
Yellow wire extension: 6Y5-82521-00-00 (is this necessary?)
The pink, dark gray, and light gray harness I assume will be left unplugged if it's for trim level gauge. I don't know what the red wire is for. And the green/green-red harness I assume needs another wire harness to go to gauge? I appreciate any advice!
