2 2 Marine Harness Introduction 1 General Motors Powertrain introduced the Marine Electronic Fuel Injection (MEFI) system in The fourth generation of the GM MEFI system is known as the MEFI-4 was introduced around 04. Double Click on the following image to open a copy of the original brochure. The AEM adapter harness is designed to adapt an Infinity Series 3 ECU to an existing MEFI-4 engine harness. The Infinity Series 3 ECU and adapter harness combination will not solve existing problems. AEM recommends checking your engine for existing diagnostic trouble codes before installing the new AEM products. A basic list of diagnostic codes is shown below. More detailed information can be found in the following manual. Double Click on the following image to open a copy of the diagnostic manual. 17 AEM Performance Electronics

4 4 Marine Harness Recommended 2 Accessories The Series 3 Infinity ECU does not have an onboard UEGO controller. The following products are recommended for accurate lambda measurements and control / X-Series Wideband UEGO AFR Sensor Controller Gauge / X-Series Inline Wideband UEGO AFR Controller ECU Connectors 3 The Infinity ECUs use the MX123 Sealed Connection System from Molex. AEM strongly recommends that users become familiar with the proper tools and procedures before attempting any modifications or additions to these connector housings.

5 5 Molex at Harness Installation 4 Tips FOR AUTOMOTIVE APPICATIONS OF MARINE MEFI HARNESS: In order for cooling fans to function via Infinity Series 3 ECU control, J1-23 of the FACTORY HARNESS must be moved to J1-. Please see pinout documentation for information regarding J1 connector. Wiring Conventions and EMI Some wire harness assemblies come pre-wired with all connectors, fuses, and relays needed to operate an engine. Harnesses that include a PDC generally require extension/termination of the flying leads to their appropriate devices, and additional sensors and other devices can be wired into the harness as needed for the specific application. The following guidelines should be adhered to while completing the required wiring. A proper wiring job includes proper termination of the wire at the sensor. The wire terminal end must be moisture tight where it plugs into the sensor and it must have strong, electrically sound terminals. The preferred method of securing a wire to a terminal is to use a crimp terminal with NO solder. It is important to use the proper crimping tool for sound terminal construction. Plastic terminal plugs must have moisture tight seals. Inspect each plug to make sure the seals are in place. Di-electric grease can be added in the terminal slots to further aid in corrosion resistance. If a splice into a wire must be made and no solder-less terminals are available, then you must properly solder the splice. Noise can be a serious problem and can cause intermittent misfiring of the engine. Every precaution should be taken to prevent interference to the ECU s operation. Resistive plug leads are REQUIRED. To eliminate or reduce the chance of EMI, wires that carry high current must run in twisted pairs. An example of this would be the power leads from a multiple spark ignition system. These ignition systems can carry up to 100 amps for a couple milliseconds at the time of discharge, which induces a strong magnetic field in close proximity of the wires. The routing of the wire loom is critical to EFI system performance and safety. The following safety considerations should be made when installing the wire loom: Heat protection: the loom should be placed away from or insulated from sources of heat. The obvious item(s) that should be avoided are the exhaust manifolds, EGR delivery tubes, and turbochargers. If it is absolutely necessary to route a wire in close proximity to any of these items, then a suitable insulator must be used. Reflective foil insulators should be used on all harness lengths that are routed in close proximity to extreme sources of heat. Noise suppression: do not route wires near HT (High Tension) leads such as ignition wires from a distributor or a CNP (Coil Near Plug) ignition system. For coil-on-plug ignition systems this is not as critical. Shielding of important signal input wires such as Crank Sensor input, Cam Sensor input, and Knock Sensor input should be addressed when assembling a harness. VR (Variable Reluctance) sensors, also known as MAG sensors, are 2 wire sensors that generate a voltage as the 17 AEM Performance Electronics

6 6 Marine Harness frequency increases of the trigger wheel. These wires MUST be wired in a twisted pair configuration with a shield. The shield should be terminated to chassis ground at ONE END of the lead while the other end is left unterminated. Failure to shield these wires with proper shield termination will result in noise on the signal and subsequent errors in the Infinity ECU. Hall Sensors (3 Wire) are not as susceptible to noise, but care should be taken into account when routing these wires. Moving component protection: route wires away from moving components such as fans, the blower belt, or the throttle linkage. Also, make sure the wires are not under any strain when the engine is at full deflection on the motor mounts. This may be hard to test, ensure that there is at least a few inches of slack in harnessing between engine-mounted and chassis-mounted components. The use of Zip Ties is an acceptable method of securing a harness from moving components. Never have the wires in exposed bundles throughout the engine compartment. All wires should be covered in a protective sheathing, at minimum, plastic corrugated loom to protect harness from abrasion. Ideally, a harness should be covered in a fire-resistant sheathing rated to a minimum of 125C, or 257F. When utilizing CAN Bus communication devices in the harness, it is important that the CAN Hi/o wires are twisted at a minimum of 1 twist per inch. When terminating these wires, ensure that there is a 1 ohm terminating resistor installed between the two CAN wires at each end of the CAN Bus. If a connected device has an internal CAN terminating resistor, no external resistor is needed. All additional controlled devices wired into the vehicle need to be wired with appropriately sized wiring. When considering wire size requirements, the following factors should be considered: Amperage of device, length of wire, heat source near wire and component. Both positive and ground circuits require equal attention to this detail and care should be taken to choose the appropriate wire gauge. Always use a larger wire gauge if unsure of power requirements of device. Ensure that ground loops are completed correctly in the vehicle including: engine to chassis, chassis to battery, ECU to chassis, etc. Ensure that when installing any additional +12v components, all power (+12v) leads should be fused with an appropriately sized fuse. Ensure that the fuse selected does not exceed the current carrying capacity of the wire used to control the component. Relays should be selected so that they are capable of carrying the load of the controlled device. Ensure that the relay has enough current carrying capacity and that the fuse in the circuit does not exceed the rating of relay. Failure to address this will result in the relay becoming the fuse, rather than the fuse in the circuit. Determining ECU ocation It is recommended that the ECU be placed in an environment that does not expose it to temperatures above 85 Celsius (160F). 17 AEM Performance Electronics
