Data Guide showing reference voltages and warranty included.

Accessories include necessary jumper wires, pin adapters, terminal sizing tool and instructions.

Below you'll find the description of each pin. Whether you're tracing down an electrical short or testing one of the input/output components of the PCM, pinout charts come in handy.

Rocker switch allows change from computer-base timing to distributor base timing. The 1994 3.0L V6 Ford Ranger is equipped with the E.E.C IV system and so its computer has 60 pins.

Matrix Board has 60 insulated test terminals.

Wire assembly is five feet long, sheathed in braided nylon.

OEM Ford circuit adapter for solid secure connection between ECA and wire harness.

Breakout Box instructions identify circuit connections and proper volt/ohm levels. Proper signal range is determined with high impedance digital volt/ohmmeter (not included). This chip is modified only for EEC and is.

EEC uses a custom Intel 8061 chip for its processing functions.

The internals of EEC are complex Intel and Ford had a joint venture building EEC. Matrix board then provides 60 terminals for system tests. EEC-IV uses the same 60-pin connector as III, but one of the indexing tabs on the outside is offset. ECM TEST PORT (J3) PINOUT ECM CABLE PINOUT EEC DIAGNOSTICS EEC FUEL CONTROL EEC. Circuit adapter connects between Electronic Control Assembly (ECA) and wire harness. Technical Notes on The EEC-IV MCU Compiled by Tom Cloud (all fonts are. Helps pinpoint cause of problems - computer, sensor, solenoid, switch, actuator or wiring harness. Thexton`s 126 Ford EEC-IV Breakout Box allows testing of all engine input signals and all computer generated output signals on 1983 and up Ford EEC-IV Computers.
