2prong is Auxillary power point and the other is diagnostic interface access.

 

Dont know,someone cleverer than me is working at Macdonalds right now, and someone will answer your question shortly.

 

As sprinter says one is - diagnostic interface access. the other 2 pin
looks like a battery charging plug as used on a battery conditioner,
(saying that it will be connected direct to battery)

 

Do the battery charge ones work both ways, to charge and to feed.

 

Yes they would feed but unfused.
(Unless he uses a fused link in the feed wire)

 

As DD says above trace the 2 pin wire in question back to battery position and check if fitted with an in-line fuse,

Most certainly an optimate charger lead same as mine. It should have a inline fuse already fitted.
