Question:

I have a 2012 Ford F150 and need a wiring harness for my 2009 Leer cap topper. What do you have available that works for this installation?

I believe you are asking about wiring for a third brake light on your Leer camper shell on a 2012 Ford F-150 (there isn't any type of wiring harness for a Leer camper shell we can offer), and for that, all you need to do is use a simple part:

- Pacer Performance 3rd Brake Light Logic Module # PP20-702

The Module # PP20-702 has three wires - two yellow and one green. You'll need to tap into your F-150's turn signals with the yellow wires and run the green wire to the third brake light on the camper shell. What this module does is filter out the turn signals and lights up the brake light when you hit the brakes.

If you take a look at the cut out of the linked installation instructions I added you can see exactly how it wires.
