What is the output voltage pulse? It's probably a lot less than 5V, since I understand a stock 5V digital signal is all that's needed for the ABS computer.
If that's the case, you can set up a simple one transistor circuit as a phase inverter with a regulated 5V off the ECU to increase the voltage output. About two pfennigs of cost.......

What's happened to all the pictures??
