I replaced that air pump relay on my RCM, had ordered 12 relays at around $2 each.
They are almost gone now, used one, gave maxchicon some and sent some to onehundred80.
I'll tell ya, it is not for the faint of heart, those suckers are HARD to remove, soldering the new one is easy.

DJ, are you back in the RCM swap business ?
( if not, can I have the spare one I sent you back ? )
