I had an older W PA where the horn unit went out.
Got a new horn/bell unit from Ma and Pa. Went to the Shack, and got some suitcase connectors, and double sided tape. Clipped off end of TBII, which looks like a computer plug to the E-Unit. Got my dummy A. Tapped red wire to red, black to black. Used double sided tape to put horn and control unit down. The bottom of the control unit is completely isolated from the frame. Placed on track without shell. Works, Placed on track with shell. Works. Placed with powered unit. Worked. Plan to get some more for my Lionel MPC units.
The True Blast 2 horn unit works with MPC era Lionel as I installed one in an MPC diesel engine a few months ago.
Also installed a T.B. 2 in an unpowered B unit, used jumper wires to the B unit from 1/32 scale remote control cars, wired it so I can run three units together, the B unit with T.B. 2 and two powered A units. Didn't find enough room inside a powered A unit, so I used the unpowered B unit.

I'm thinking of my 6-8467 Amtrak F3A dummy!
That should work, tie into the headlight wires if so equipped.

Yes, that unit has a headlight.
