Bosch L-Jetronic ECU connector plug

[martinr82]

Hey Guys,

Another completely random question.

Does anyone know what the connector is called for a car running a Bosch L-Jetronic that connects the loom to the ECU? I am basically looking for the part inside the ECU, plug to PCB, so to speak, not sure if something like that exists, without bastardising an ECU and de-soldering one.

What I am trying to achieve is maintaining the original loom in the car, but connecting to a megasquirt or Emerald ECU. However, its not a simple as that, I want to utilize the original loom for the most part, so that the car can be put back to the original configuration fairly easily, hence needing the connector. The idea is to make an "interface box" that will allow me to hook in a coil pack, which will replace the dizzy, a cold start valve to replace the supplementary air device, a flywheel sensor, a MAF instead of an AFM and finally a lambda sensor using separate cables which can be stripped out to return the car back to normal.

I know old skool Porschi, BMW and a smattering of other vehicles ran the L-Jetronic, so wondered if anyone has done anything like this, or seen it on a forum somewhere that might give me a bit of direction.

Thanks

Martin

Just cut the existing loom and fit new male and female plugs (of any make) to join it back together. Then using matching plugs make up the new section to join into the standard emerald or megasquirt ecu plugs. I'm not sure any of that makes sense ?

Hey Ed,

Thats exactly what I was trying to avoid. I want to keep the existing plug and make a "conversion box" to be able to revert to the L-Jetronic with relative ease.

Basically, as soon as you start cutting the original loom, its less original.

I did this with a 21 Turbo. You can't get the ECU plugs separately on the ECU side, you have to de-pin it off the circuit board. It was never a very elegant solution though and in the end I made a whole new engine loom.
