ago with a junk box one that has heavyduty silver contacts, and have had no 
trouble
since...It requires a single pole double throw so I just used the 
appropriate contacts
on the relay I had...I think the old one was double pole, double throw, but 
half of
is was not used...

Mine is a 22c from KLM, but I would imagine there is little difference...

As I remember I THINK I hard wired it, I'm sure the replacement had 
different spacing,
and I just hard-wired it...low voltage there so nothing is critical...
