Cheers!

This LH module is located under the hood, in the aluminum computer box (same area where you will find 38 pin diagnostic port, same place where the E-Gas module, and such, once the cover is opened, you will see all of them stacked in the row, basically the computer brain for these non-CIS pre-face lift cars)

Some curious minds figured out that that some early models of W140 fitted with M119 5.0L engines were equipped with LH modules that were a little different from the others, they had a Wide Open Throttle enrichment, basically "richens the mixture" at WOT... And when dyno tested, depending on the condition of M119 engine, once fitted into compatible non-W140 car, would provide additional horse power, certainly not a huge amount, but up to 10HP in some cases. Very popular mode with w124 E500E owners. Personally, I will take any known and proven upgrade/update for m119 I can get my hands on. And these are affordable.
