Need help wiring OTRATTW switches

I have been putting of a bunch of wiring jobs due to lack of knowledge. It's time. I have a cool switch panel that holds a 6-pack of switches from @Iggy and I want to get them working to lights/accessories and I would like them to work with the factory dimmer.

I'm looking for help checking my diagram to make sure it's correct and I also need advice for wiring the OTRATTW switch in the cab.

In this example I am wiring a 20" LED bar:

* Blue Sea fuse box is connected to the (+) and (-) terminals of the battery

* (+) on the Blue Sea will go to the 30 pole on the relay and the (-) on the Blue Sea will go to 85 on the relay

* 86 on the relay will go to (+) on the LED bar

* (-) on the LED bar will go ??? - Should I run this to 85 on the relay or just ground to the chassis?

* 87 on the relay will go into the cab and connect to 3 on the switch

Questions:

1) Does this look to be correct so far?

2) How to I wire the rest of the switch in the cab for illumination/dimming? e.g. 2, 8, 6, and 7 on the switch?

Here are diagrams for the switch, relay, and my sketch of what I think will work up to this point:

 

i am kinda lost on all your diagrams lol.
but do like this for the lights. and use your diagram for the light.

 

Can't help with the dimming circuit, didn't hook my switch up to it. Hope this helps, best I can do at 4am, lol.

 

Thanks guys. Per the relay diagram, regarding 85 and 86, it says 'One of these will be used to ground your current, while the other will be connected to a switched power source.' The diagram shows 85 to ground and 86 to switched power which is the opposite of the diagram from @paranoid56. I'm thinking it may not matter what one goes to (+) or (-)?

I made some changes to my original diagram connecting 87 to the LED bar and 85 (or 86 - whatever is not connected to ground) to the switch. So...as long as the updated diagram is correct, I just need to figure out how to wire the switch

It looks like I need to connect the battery directly to the switch so I have a fused line going to 2 on the switch. Switched power on the relay, 85, is now going to 3 on the switch.




On the switch 8 could tap into dash lights. Chassis grounds for 6 and 7? Is that it?
