It is probably 2' wide. Maserati definitely took Picoscope diagnostics seriously.

Interesting I have been doing a lot of work on break out box design, I have one design based on units of 26 pins which is interesting.

There are some issues with break out boxes and one of them is bulk.

Can you imagine tring to drive a car with the Maserati break out box.

Another thought that I have is to simply make extension leads. Even there one can have options, straight extension, Y extension or V extension.

One could use a factory header connection on the V or Y , then one could either connect channels into each pin or bake probe the denuded connector housing.

That results in a very cheap , compact and effective break out system.

I have seen pictures of Ian's breakout leads. They are second to none!

TBH, I can't even remember where the PCM is on most of the Maseratis. It wouldn't be too bad in a newer Land Rover as the PCM is right next to the brake booster and is very accessible. The cables for the Maserati breakout box look long enough to reach inside the car.

Hello, fellow nerdz. I do a lot of harness repair and something just hit me - I see improper back probing every time, and I see it is all publications /videos/conferences that are held by pro auto techs. Most people back probe in a way that damages the weather seal of connectors. If you have never taken apart a connector, you will do something that seems logical but will end up damaging weather seals.

Thank you K-Mech! I am one of the ones who was doing this incorrectly, but not anymore! Wink
