Sorry to be so long winded about this...but there is a complication with the wiring as it is.

Although it will work in theory, there is an issue which could be responsible for blowing your fuse.

They have the D pin wired to the signal that goes from the 4th gear switch to the solenoid. That means that when the 4th gear pressure switch is closed, voltage not only appears at the solenoid, it also appears on pin D. If the device connected at PIN D, is at ground signal (for whatever reason), then it will most definitely blow the fuse.

What are you using PIN D for? Do you have a manual switch for towing? That is typically what this type of circuitry is used for.
