The new 324-7875 Control Box Gp (1) replaces the original 242-8988 Electronic Control Gp.

The new control box is adaptable to the above engines back to first production.

For engines that are already equipped with the new control box, the new 353-8089 Electronic Control Gp (2) inside the box can be serviced separately.

All applications and engine arrangements use the same 381-8821 Engine Ratings Electronic Software Gp.

The new control box and the original control accept the same harnesses from the thermocouples. The new control box requires different mounting hardware.

Note: Because the new control box is thicker than the original control, the scaffolding for engine work may require modification in some cases.

Refer to Table 1 to look up which kit will work best with each engine. Keep in mind that these kits do include the 324-7875 Control Box Gp.
