Greetings All,
I want to use my Aiu's Acc ports to act like a toggle switch.
I want to power and kill power to my sidings.
Can and how would I wire it?
I don't want to fry the Aiu.
I have the switch side working great.
Thank You.

The short answer is that since the AIU relays can only handle 4 amps each, you need to either limit siding power draw to a maximum of 4 amps or use the AIU's ACC port to control a second, heavier-duty relay.
If you have a copy of The DCS O Gauge Companion 2nd Edition, refer to pages 87-88 for a complete discussion of this subject, including step-by-step instructions for implementation. It's a bit too much to copy into a post.
This and a whole lot more is all in MTH’s “The DCS O Gauge Companion 2nd Edition", available for purchase as an eBook or a printed book at MTH's web store!
Pro Hobby I see you didn't use the MTH terminal blocks. Are these ones like at Radio Shack, and are they about as easy to use?
Mark,
What you're seeing in the photo aren't terminal blocks and, as shown, don't function as them.
They are, rather, barrier strips. These are like the Radio Shack product and may be connected to function as terminal blocks. However, the MTH terminal blocks are superior to barrier strips that are connected to serve as terminal blocks.
Thank you once again for clarification Barry. You truely are a gentleman and a scholar!
Terminal blocks used for wiring the control system.
I use 2 different types of terminal blocks depending on the "size" of wire.
The 12 position plastic terminal blocks have screw terminals and a plastic snap on cover. These are useful for smaller wire sizes #22 to #18 AWG.
The second style terminal strips are also screw terminals but can accept wire sizes from #18 to #14 AWG.
Pro Hobby,
From the picture you just posted, this are barrier strips, not terminal blocks. I am very familiar with both types.
I cannot see any jumpers that would connect the terminals.

You are correct. These terminals are not used with jumpers but allow connections from the TIU terminals directly to external convenience terminals. The plastic covers are installed on the "barrier strips" to reduce accidental short circuits between wired connections. The attached barrier strips also have numbered terminations.
