brakes lights on 1998 Ford Windstar

brakes anti lock lights were not coming on before new motor

Asked by for the 1998 Ford Windstar
Are you saying your red brake warning light and anti-lock brake warning light are both coming on?

It would be advisable for you to check all wiring connections to the front wheel sensors. Since your subframe had to come out, your axles had to come out and the wheels had to come off in order to replace the engine, it is possible one of the wheel sensors or wiring for the sensors are compromised.
