content: I'm trying to identify the attached connector. It's off a Webasto thermo pro 90 heater. We need to buy replacement plugs and mating halves, They don't seem to know themselves what the plug is.

content: It certainly looks like some superseal variant, but I've never seen one of those with mixed contact sizes...

content: Can you check if there are any markings/logos on the sides you didn't photograph. It should have FEP / DRN / TE or some other manufacturers ID.McBryce.

content: Well you can still buy the one end of the connectors from places like this:http://standheizung-ersatzteile.com/standheizungen/ersatzteile-und-zubehoer/webasto/elektrische-zubehoerteile/24672/stecker-sg-thermo-90s-kabelbaum-heizgeraet(The Webasto Part Number is also mentioned on this page), but it would probably be a lot cheaper if you knew who made them, especially if you need a lot of them.They seem to be rather old connectors (they use double-spring contacts that are rarely used these days). If you need to swap both sides, wouldn't it be easier to just find a suitable 3 pole connector?McBryce.

content: The only way I know to get the male connector is to buy the controller board and rip off the connectors. They are press fit AND soldered, so there might be som effort involved.Since they are a supplier for the automotive industry, it's likely to be a custom connector. Molex has similar ones, but they're not a match, as far as I know. Granted, I wasn't looking for a 12-pin connector, but I suspect it will be the same story.I've had to replace connectors on older machines before, and it's way easier to just pick a new type that's abundantly available and refit all the machines. And I was dealing with more or less standard industry systems.Of course, you could contact Webasto and ask, might be worth a shot.

content: The problem is that the other half of this connector is molded into the ECU body of the heater.

content: OK, well, I had a spare one to destroy. Since Webasto doesn't repair it's controller boards, you might try and buy a broken one, if you can.
