R5 Trim Tab Location

After reading and contributing to the R5 in rough water thread, I'm convinced that I do need to invest in Trim Tabs. To that end, I would like to see some pictures of where the Trim Tabs are located on member's R5s. Can some of you fine people post some pictures.
Also, I spoke to the factory and they shared some information which may be helpful to others.
The boat is pre-wired for Lenco Electric trim tabs (as tgrace98 posted)
The OEM part number is Lenco #10955-103 which is a 9X12 tab
The hardest part may be getting the wires unbundled from the wiring harness and working in the engine compartment which can get tight
I also called Lenco and they confirmed the OEM number above that is not listed on their website, but you can buy the same kit from Lenco which is part numbers:
Basic - 15101-104 - No Auto retract or LED lights on control ($512.12 on Boatplicity with free shipping)
2nd Best - 15104-102 - Auto Retract but no LED lights on control ($576.63 on Boatplicity with free shipping)
Best - 15108-103 - Has both Auto retract and LED lights on control ($730.16 on Boatplicity with free shipping)
I think I'm going to spring for the Best option because it's my Cobalt. My local dealer quoted me verbally $3,000 to install them. After watching some videos, I feel like I am comfortable taking a shot at it. Has anyone on the forum installed their own? Are there any tips or lessons learned?

We have the “best” option mentioned above (although made by Bennett). Same features though. The LED’s are a must have. Auto retract is nice if forgotten.

I wonder if the older boats were pre-wired for tabs?

Call up customer service they will know for sure.
And back to the topic. Option 3 for sure as that is the way they come from the factory. So once installed will look oem

Factory TT pic on 2020 R5. Auto-retract a must for me - especially being in dry stack. Couldn't imagine not having LEDs either...

Here’s my 2014. Lenco’s with auto retract. This is my first boat with trim tabs and I wouldn’t have another boat without them.

You are hilarious... to yourself! Actually, I would love to have them installed by then, but it has been so hot in Texas that I don't think I would survive the process. Plus, I'm working on buffing the boat for TRL. I started Friday and spent about 3 hours on the Starboard side. This is my first time doing this and it is an A$$ kicking. The work itself isn't horrible until you have to hit the same spot for the umpteenth time. Fortunately, there is only two spots with fender rash, but I'm learning how to be patient and change buffing bonnets. It is very slow cleaning up the worst spots butI feel like a pro when I'm buffing the rest of the boat because that starts to shine very quickly. I plan to bring all my stuff to TRL, so maybe some of you weirdos can show me how a pro does it.

Thanks Greenhut. Great picture. I'm feeling more confident by the second.

So, it seems like every cobalt I see with trim tabs has the swim platform is raised up several inches. This makes it harder to get out of the water with the swim step, I am not sure the reason for this just an observation. It may be just in the R'series. Has anybody else noticed this?

I think you are seeing things. They do not change the mold for trim tab as they can be added after the fact.

You are seeing things. The swim platform and step are the same with or without trim tabs.
