What wire colors feed the headlamps in this diagram?

Circuit 12 is LG/BK (light green/black), circuit 160 is DB/WH (dark blue/white), and circuit 161 is DG/OG (dark green/orange). Ground circuit 57 is BK (black).

What are the headlamp connector numbers?

The left headlamp uses connector C143 and the right headlamp uses connector C133. Power comes from C242 and C243 (page 85-1), through inline connectors C159F/C159M and C160F/C160M.

Where do the headlamps ground?

Both headlamps ground on circuit 57 BK. The left headlamp goes through splice S105 to ground G102; the right headlamp goes through splice S104 to ground G103. See grounds page 10-6.

What circuit connects the headlamps to the instrument cluster?

Circuit 932 GY/WH taps off splice S218 and runs through connector C236 to the instrument cluster pin 12 (page 62-5).

What splices are used in the headlamp circuit?

Splices shown are S218 and S114 on the LG/BK circuit 12 feed, and S105 and S104 on the BK circuit 57 ground paths.

This is page 085-002 of a Ford factory-style wiring diagram covering the headlamps circuit. It shows power feeds arriving from connectors C242 and C243 (referenced on page 85-1) through three circuit branches labeled A, B, and C. Circuit 12 (LG/BK, light green/black) feeds low beam power, passing through splice S218, inline connector C159F/C159M, and splice S114 before reaching the left headlamp at connector C143; a tap of circuit 932 (GY/WH) goes through C236 to the instrument cluster (page 62-5), presumably for the high-beam indicator. Circuit 160 (DB/WH, dark blue/white) and circuit 161 (DG/OG, dark green/orange) carry the other beam feeds through C159F/C159M and C160F/C160M to the left headlamp (C143) and right headlamp (C133). Both headlamps ground through circuit 57 (BK, black): the left headlamp through splice S105 to ground G102, and the right headlamp through splice S104 to ground G103, with a note to see grounds on page 10-6. The diagram lets a reader trace wire colors, circuit numbers, connector and splice IDs, and ground points for diagnosing headlamp low/high beam faults.
