I'm in the process of installing a L-Jetronic Fuel Injection System on a 1975 Porsche 914 2.0L engine, which I'm installing the engine etc. in a 1970 914 body. The FI system was reportedly from a 1975 914 engine along with the engine. I'm needing some good photos or good diagrams that will help locate where all the wiring goes.
Items I've been working from: 1) Haynes 914 Owners Workshop Manual 2) Internet flow charts and electrical charts From the attached photos, you can see on the FI wiring harness I have several wires that are hanging loose. I believe the ones on the p/s the 4 wires together go to the MPC Sensor in the picture. Anyhow any help would be appreciated. From the picture you can see I have the wires going to the 4 injectors hooked up, not sure if they are going to the correct injector but I don't think it matters! When I purchased the 2.0L Engine it had twin carbs on it, it possibly had some parts removed. I think some of the wires go to the following items: 1) Cylinder head temp sensor 2) EGR Valve (which isn't going to be used on exhaust) 3) MPC Sensor (4 wire plug in) 4) Intake Manifold Temp Sensor 5) Thermostat Switch 6) Cold Start Valve 7) Engine Speed Relay 8) Throttle Valve Switch 9) Vacuum advance Disconnection 2-way valve 10) To starter terminal .....Maybe I've answered my own questions?
