I need to pull the ECM fuse on an '89 Trooper, but can't find a location description. Anyone know this one?

Thanks in advance.
The relay is located in the fuse box.

That's probably it if it's in the fuse box. Not to be confused with the "Main" relay which is hidden over on the passenger fenderwell.

The manual shows 2 fuel pump fuses. These are numbered 23 & 24. Fuse 23 is also designated as the ecm controller. Both fuses should be 20 amp.
