Hello,

So I installed an Optima 650 ($140 at AutoZone) battery:

And bought the Aux Battery kit from GoWesty.

It was a seriously irritating installation.  First of all, the battery
terminal posts are conical, so the connectors in the kit just slide right
up and off the posts as you tighten them.  Second, the wires in the kit
are really short (as are the VW wires on the relay).  I ended up splicing
extensions and replacing several of them.

Somehow I managed to screw up the wiring to the relay.  Does anyone have a
picture or wiring diagram of the relay?  It appears that the stereo is
being powered from the aux battery when the engine/alternator is off, but
I don't have any electricity to the sink, water pump, frig, or LED panel
when the alternator is off.  As soon as I start the engine I can use the
sink and run the frig on 12 volt.

Thanks,
Matt
