Hi Jay, 1) The wire is probably for the ABS sensor on the pinion shaft.
2) There are only two different rears, both are 2.87:1 ratio, but one is limited-slip (ASD) and the other is not. If you car has ASD you need to use special Mercedes fluid. If it's not, you can use Mobil-1 or any other correct weight/rating gear oil. If you have a 'warning triangle' in the middle of your speedometer, above the odometer, the car has ASD. :-) -dm > ------------------------------ > Date: Mon, 11 Jul 2005 11:48:21 EDT > From: [EMAIL PROTECTED] > Subject: [MBZ] 95 E300D rear > > > Two questions. 1- What is the wire for that connects to the drivers side of > my rear diff? 2- My owners manual shows 3 different rears and they all use > different fluid.
