Whats this? Challenger 1800 extra parts

[johnnypinaz]

Does anyone know what these are for, can be used for or where they lead to? These are next to the battery...



And how about this one? Behind the dash...

I believe that the 3 extra connectors are for some diagnostic tools… maybe just an external tachometer.

The 3 connectors in the top pic are fuse holders containing 3 separate 20-amp fuses that are power sources to the boat (not engine). They are located and connected to the main battery disconnect. The Seadoo shop manual for the Challenger/Speedster/X-20 show the fuses and what they feed.

The second pic looks like a capped connector behind the dash for something. Not sure what... perhaps a gauge you don't have or a diagnostic connector. I don't have this connector on my boat.
