1990 Ford Bronco Connector Pinouts: MLPS, Main Light & Tailgate Window Switch

This document is page 150-14 from a Ford connector faces/pinout charts reference, showing connector face drawings and pin/wire identification for three components: the Main Light Switch, the Manual Level Position Sensor (commonly associated with the E4OD transmission MLPS), and the Master Tailgate Window Switch. Each diagram shows the physical connector face with callouts identifying circuit numbers and wire color codes. The Main Light Switch connector uses circuits 484 (O/BK), 137 (Y/BK), 38 (BK/O), 54 (LG/Y), 195 (T/Y), 15 (R/Y), 14 (BR), 55 (BK/PK), and 19 (LB/R). The Manual Level Position Sensor connector uses circuits 32 (R/LB), 199 (LB/Y), 298 (P/O), 359 (BK/W), 140 (BK/PK), and 33 (W/PK). The Master Tailgate Window Switch (a feature found on Broncos and similar vehicles with power tailgate glass) uses circuits 400 (LB/BK), 57 (BK) at two pins, 404 (P/LG), and 405 (P/LB). A reader can use this page to identify wire colors and circuit numbers at each connector pin for diagnosis of lighting, transmission range sensor, or tailgate window electrical problems.
