So I went to reinstall the 3 batteries in my Brave now that winter has finally left us, and found my hand drawn schematic of how it all connects had gone missing .You know the important papers you have that you put in that safe place...  And my backup picture on my smart phone can't be found .   Not a good start .

How hard can it be ?

Connected the chassis battery and she started right up !  Always good news !!!!

Now to the two coach batteries .  So there are two negative cables and two positive cables, along with a "jumper" cable for each positive and negative post to "tie" the two coach batteries together . One of the positives had a big clamp type thing on it, assuming it is some sort of fuse type thing but since the batteries are tied together did it really matter which positive post to connect to ?!   Doubtful so connected them all up and the lights inside the RV now all work  

Great right !!!!  Nope .There are still two thin cables left over . One is white and the other is black mostly with a small fuse like connector and a thin similar gauge yellow wire coming out of it .

My question is where do these two cables connect to and what are they got ?  They kinda look like ground wires but isn't that what the negative cables look after ? They seem to come from the same location but I can't trace them at this point . I have a schematic that is more a high level, that shows you can tie the coach batteries to the chassis battery for emergency starting, could it be related to the relay function for that ?

Either way I need help where to connect these last to cables .  Makes me a bit nervous if they are not connected properly. 

Thanks in advance for any help you can provide !

Thanks...Art

2) 12volt batteries in parallel, correctly

I'll start here,

Hi postman . So if I have two positive cables should I be connecting both to the same post on battery1 and then use the jumper cable to battery 2 positive ?  And the same for the additional negative cable . Your diagram just with the additional extra cables ?

Yes, I questioned that you had 3 pos(+) and 3 neg(-) connectors.

First, follow the neg(-) cables to the frame. There's a factory ground buss bar expected in the battery bay. Also I would expect a battery isolation solenoid. Here's pics of battery bays, oops gotta find the other one.

Now that is impressive,, well organized,,,

LOL yeah, then theres mine!

Here is a military battery clamp I ordered

LOL, Lakota come on! That aint helping. (god I need a smiley!)

Ok back too the beginning. Art detailed description of your three batteries, I assume are flooded. 

I just added the schematic .   As mentioned u able to trace the cables right now .

Yes there are 3 positive and 3 negative . One of each for the starting battery and those are connected time.  

The remaining two of each i thought I connected 

Properly to the coach batteries but your diagram implies i need to redo

My spell check on my tablet is overwriting .  Sorry for the terrible writing . 

And yes - flooded
