anyone can help me find this part number?

It's either:

124 440 56 32 (earlier production run)

or

124 440 29 33 (later production run, more expensive)

Check the tag located about one or two feet down from the bulkhead connection behind the battery before ordering a new one.

Yes, it does matter. On my vehicle I was initially sent the wrong one by mail-order that didn't fit (even though I offered to find the part number before ordering). That's how I know there are two different styles for this vehicle. Look up the number on your wiring harness before ordering.
