There are two types of underseat plugs - early type (up to maybe 2001/2) is bigger and the metal connectors prone to seat foam outgassing causing tarnishing/corrosion. Later type is smaller and MGR did something to stabilise the foam and I think the connectors were gold plated (really). By all means do a light clean/lubricate on the plug connectors but check out MGR Technical Bulletin TB0133 iss2 (27/08/2004). The biggest issue is the cable routing combined with seat movement/adjustment putting a slight strain on the connectors (MGR called it fretting) which go to high resistance and the dreaded light comes on.
I re-routed per TB and it's never given a problem since. A cable tie across the male/female plugs is also a quick fix to prevent any small mutual movement.
