Pulse generators

[ronjefferson]

I recently did an engine swap on m 94 3000gt sl. Its an auto. Here are the issues I am having. The od light is not working when I hit it. I know that could be simple as a blown bulb. The car is staying in 3rd, "limp mode". It does not change to L, 2, just stays in 3rd. Ok, there are 2 plugs under the air intake box. I am fairly certain these are, at least one, the pulse generator plugs. My question is, I can not figure out which way they go in, does anyone have pics they could provide me with or a wire to wire diagram. The plugs themselves are broken and I am going to solder them to prevent further damage. Help is greatly appreciated.

That is a common issue as the plugs are the same and right by each other. Only way to check is look at a diagram and match colors or try one way then swap them. It will
Not damage anything to swap them, I have done it a few times. You swapped just the engine or the trans to? The trans itself must be matched to its corresponding tcu or the solenoids will not work properly.

Another simple check is the fuse. Should be fuse 7 in the underdash fuse box. Same thing happened to my cousin.
