Fuse for Electric Brakes

All,

2005 Chevy Av Z71
Has factory 7 plug trailer connector.

I have a surge brake trailer.
Thinking that the 'electric brake' wire overrides my surge brakes from locking when backing up.

Where is the fuse for this? 
(Easier question - where are all the fuses that would be in play for the trailer plug / wires?)

Dropped the boat in a little far this weekend w/ the trailer plug in.  thinking it may have blown the fuse - because I can no longer back up my trailer w/o the surge brakes locking (no manual override on this trailer either). 
(Oddly, trailer & truck lights, turn signals, backup lights still work)

The owners manual mentions something about Trailer fuse in the center instrument panel fuse box - but I cannot find this center instrument panel box location? (underneath instrument panel - ie: do I have to take apart the dash? - Not seeing anything upwards of the floorboard?)

I checked the 15s in the interior side and under hood locations - but those were good.

Any help / direction appreciated.

Thanks
Jason

 
Under hood fuse box.

But "SURGE" Brakes are not electric at all so would not matter.

Surge have master cylinder built into trailer tongue and when you are going forward and brake the momentum of trailer presses on this master cylidner creating brake fluid pressure sent back to brakes on trailer wheels be drum or caliper.

I understand that... but in order to back up with a surge trailer (without activating the brakes on the surge trailer) - the harness needs to send a signal to the actuator to not engage. (Electric reverse lockout solenoid feature)

Maybe Im thinking this wrong - thought the connection was coming from the electric wire - but maybe signal coming from the backup lighting wiring?  (will verify later tonight)
 
would come from reverse
look for fuses with TRL in first part of fuse description.
Bunch of them' 1 for each wire I believe
 
My trailer for my 25' Tracker Party Barge has surge brakes.

There is no electrical connection to the surge brake device.

In order to back up without the trailer brakes engaging, there is a place on the surge mechanism at the trailer tongue that you insert one of the trailer chain hooks to prevent the surge piston from activating.

This is by design.

Before I back my trailer into my storage barn, I have to exit the truck and insert the chain hook into the surge brake to prevent the brakes from engaging as I back up the slight incline into my storage stall.

I DO NOT have to do anything before I begin to back the trailer DOWN the launch ramp.

The weight of the trailer pulling itself down the incline of the launch ramp prevents the surge brakes from engaging.

The only time the surge brakes engage is when the weight of the trailer is pressed toward the truck, as in normal stopping action or when trying to back the trailer up an incline.

You CAN engage the surge brakes if you attempt to back up the trailer on level ground too fast.

Reverse slow and steady and the brakes should not engage.

Most of the time, the surge braking is a no thought process, for my trailer.

Hope this helps.
