What the locking of the rear brakes go, you have to adjust the brake pressure proportioning valve, all bravo/a have them till 1999, after that they came with EBD+ABS.
What the ABS light goes, if you didn't replace the sensors, or used wrong ones, or they ain't working right - you automatic have a fault.

You need to go to a mechanic - he should check if you have the valve and if so adjust it.

Number 10 on the pic - for further info you will have to wait till afternoon.
The valve is located (if you dont have EBD) on the ""rear axle"".

If there is no valve - you have EBD and dont have to adjust anything.
What the ABS goes, when the light is ON the ABS is OFF. So you have regular brakes.
Did you do anything else on the car except the engine swap ?

Dont know whit what diag equipment you read out the code, and do you have a OBD plug or normal 2wire fiat one, but its the only code I found.
And what the relay goes, its on of the relays right of the steering wheel where the fuses are, plus like Tom said, fix the sensors first, it may be that all will be OK after new ABS sensors.
