Fuel pump relay part# 1988560sel
 

Hello out there :) Can anyone tell me if there is a oem replacement from the 9 pin fuel pump relay to the 10 pin and if there is a diffrence and or will a 10 pin one work or is this a new replacement for the 10 pin one. When I, look up part to be replaced from www.mbwarehouseparts.com and all other oem original parts stores they all show the 10 pin one. Mine had a 9 pin but just replaced 2 new fuel pumps and like always you should replace the relay also as I did purchase but I recieved a 10 pin relay. I just want to be SURE not to short out or overload system or new pumps. ThankYou in Advance.:)

im 99% sure I have one from the 89 420 Sel that im parting out.
