If it is something like the memory
line to a stereo, it might have a capacitor on it...and that might account for the higher initial draw...while the cap is charging, and then the steady state of 2mA is what it draws after the cap is finished charging.
BTW, it might not be wired to the positive battery terminal, but to the battery switch or some other place you'd have an always hot 12 VDC connection.
If you don't have any wires that could be such a leak... then you're up to checking the Ground Leak, which is the second section of that post.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
