What wire colors do the fuel injectors use on the 1987 Crown Victoria 5.0L EFI?

All eight injectors have a RED feed wire; the signal wires are: #1 TAN, #2 TAN-WHT, #3 TAN-YEL, #4 TAN-BLK, #5 TAN-LT BLU, #6 TAN-LT GRN, #7 TAN-ORG, #8 TAN-RED.

Which ECA pin controls the fuel pump and what color is the wire?

Pin 22 of the Electronic Control Assembly is labeled FUEL PUMP and uses a TAN-LT GRN wire, running through the fuel pump relay and inertia switch (PNK-BLK / BLK) circuit.

What are the throttle position sensor wire colors?

The throttle position sensor uses ORG-WHT, DK GRN-LT GRN, and BLK-WHT wires.

What wires go to the TFI ignition module?

The TFI ignition module connector shows RED-LT BLU, BLK-ORG, YEL-LT GRN, DK BLU, RED-LT GRN, and WHT-LT BLU wires, with the ignition coil connected via WHT-LT BLU and RED-LT GRN.

How many pins does the ECA (engine computer) connector have?

The diagram shows a 60-pin ECA connector for the 5.0L EFI Electronic Control Assembly, with pins numbered 1–60 and functions/wire colors labeled for each used pin.

This is a scanned Mitchell Repair Information wiring diagram labeled 'Fig. 2: Engine Compartment (Cont.)' for the 1987 Ford LTD Crown Victoria, covering the 5.0L EFI engine's EEC-IV engine management wiring. The centerpiece is the 60-pin Electronic Control Assembly (ECA) connector, with each used pin identified by function (KAPWR, ISC, FUEL PUMP, HEGO L/R, IDM, ACT, MAP, VREF, SIG RTN, ECT, EVP, TP, STI, NDS, CANP, injectors 1–8, SPOUT, PIP, STO, V PWR, grounds, etc.) and its wire color code. It shows all eight fuel injectors with their individual TAN-based wire colors, the idle speed control solenoid, EEC-IV self-test connector, fuel pump relay and inertia switch, EEC power relay, MAP sensor, manifold charge and engine coolant temperature sensors, EGR valve position sensor, throttle position sensor, canister purge solenoid, thermactor air diverter (TAD) and bypass (TAB) solenoids, EGR vent solenoid, A/C wide-open-throttle relay, both left and right O2 sensors, the TFI ignition module connector pinout, ignition coil, starter relay, gear selector switch, and radio noise capacitor. Readers can trace any engine-compartment EEC-IV circuit by pin number and wire color. The page is dated/printed February 13, 2004, © 2003 Mitchell Repair Information Company, LLC.
