Hi Andy
That will be the ABS ECU/Contoller unit for the braking system
The other is the ABS Pump
I would list sepperately
I sold my Sierra ABS pump for £25 ( On a buy it now ) & Sold the ABS ECU for £15 ( Also on a buy it now )
Had to list them a couple of times but as allways, purely depends if someone is looking for one at the time !!??
Don't forget to watch out for free listing weekends
