Humminbird has installation cheat sheets for some of their products available as individual downloads or as a single PDF file ---> Here (https://www.humminbird.com/support/installation-diagrams?utm_source=ascent360&utm_medium=email&utm_campaign=hb_200521_Installation_Diagrams%20remainder&utm_term=MjUxMTk2ODU4MzgS1&utm_content=5417016&bc_hash=7bc12c158bbb72f9bebbee9526992ce7&spMailingID=5417016&spUserID=MjUxMTk2ODU4MzgS1&spJobID=1021000909&spReportId=MTAyMTAwMDkwOQS2)
For the entire bundle look for the undelined link that says "download the complete set of PDFs" or you can browse through different configurations and download individual PDFs only for the ones you need/want.
Hope someone can find them helpful. ~sun
