Fuel relay part numbers .. 300e - PeachParts Mercedes-Benz Forum

I just bought a fuel pump relay for my early 86 300e.. the -up to -a### whatever..
its the 9 pin 002 545 27 05.
What i got was an 003 545 24 05, the ten pin later model. The part is marked with the 002 part number. Is there any chance this is interchangable and that the 10th pin is just unutilized when used in an early 86 300e?

I know it sounds silly, but they claim that electronic parts are non refundable, and i'm sitting on a 70 dollar core charge and a 70 dollar relay, want to get my money's worth.

Almost a blessing, as i've found one for 40 bucks.. but i've already got this one.

the one that you got 003-545-24-05 is supp to fit after chassis a396765.but if you give me the spare pin # designation and all the other pin #'s match i will tell you what it's for and whether that relay will work.

I called programa, the reman company. They claim it WILL work and not all pins are energized in some applications. This is what they sent.
SO.. i still think its wrong.. but they say the'll make it right.
Think i'll hold off till i get a reply from the place i bought it from.

"Hello,
The part numbers that are equivalent to the 22705 are these:

Customer P/N
002 545 2705
05 89 5659
89 84 2289
89 84 2289 M08

Do not go by the amount of pins, many times some pins are not active (not connected). If the unit is labeled as 22705 proceed to connect it. If it does not work, then contact us so we can get you a replacement. Please let us know who was the distributor ?"
