This scanned page is from a Ford factory-style wiring/connector location diagram showing pin-out details for connectors labeled C-530 and C-532. Connector C-530 covers three related connector part numbers — 18B821, 18W862, and 18A919 — which mate together behind the instrument panel near the conventional radio; a note states that all connectors are grey. Wire circuits shown at these connectors include 722 GR-R (green-red), 721 BL-GR (blue-green), 137 Y-BK (yellow-black, shown doubled '(2)' at 18A919), 723 BL-O (blue-orange), and a B BK (black) wire on 18W862. A dashed circuit 268 R-BK appears at the top of the page from an adjacent diagram section. The lower section, C-532, shows a multi-pin connector 18B919 with circuits including 724 GR-W, 716 Y, 721 BL-GR, 718 R-W, 57 BK, 713 W, 710 W-G, 720 BL, 722 GR-R, 137 Y-BK, 717 BL-R, 709 W-BL + 713 W, and 715 GR; the bottom rows are cut off. A reader can use this page to identify radio-area connector shapes, wire circuit numbers, and color codes for tracing dash wiring.
