Hi Can not find the engine loom to body loom 26 pin connector for a ~96 Jdm 1UZ FE. The Ecu is a 34/22/16/28. This is the body loom connector, that does not match with colors in the 80/40 ecu.

Cant find in the forum. So, what is the manufacturer compression pressure of a 1 uzfe (out of crown magesta)?. Mine has around 210.
