removing my Tekonsha brake controller, need help

[okieinalaska]

I want to take my P3 off my old truck to put on my new truck. I'm selling the old truck and want to keep the controller.

I looked at it and it just plugs in to the box under the dash. But for the life of me I can't pull it out! Is there some trick, I need to push in one side or there is tab to lift or something? I can't unplug it. Someone is coming tonight to look at the truck and I would like to have it off before then.

Also will I be able to just plug it into my new truck and attach under the dash or will I need a new wiring harness? Going from 2005 chevy silverado crew cab 1500 to
2013 chevy Silverado crew cab 2500 diesel.

Thank you,

I have a P2 - not a P3 - so mine may be different. But mine has two small tabs on the outside of the case, at the front of the sides that have to be pushed slightly to allow the controller to come out.

I have the P3 and just checked the connector. There is a locking tab at the top. I stuck a key under the tab (come from the front of the controller) then pull the harness out.

Looks like the 2005 Silverado uses the 3015-S harness but I do not see a harness listed for the 2013s on Tekonsha's site.

I got it! I used a flat head screw driver to push the tab and got the wiring harness unplugged from the truck. Then I unmounted the sleeve and the controller.

Now my problem is I can't get the little fuse box panel back on. I didn't pay attention to how it came off and I can't figure out which way to turn it.

I called e-trailer and there is no plug in ready to go wiring for the 2013. I think Chevy stopped the plug in thing in 2007 I read. Instead I would have to pull the wires and connect them and crimp. I have a built in brake controller already factory installed but wanted the prodigy. I can probably just give it to my brother instead and live with what I have.

Thank you for your replies!

Yea on my P2 just had to unclip the harness at the controller but I had to tie it into the factory harness gm had tucked up under the kick panel for a brakecontroller when I installed it. Luckily e-trailer had a video for wiring one up for the envoy/trailblazer so super easy. Looking to add some quick disconnects to the harness plug or just buy another P2 harness so I can share it between TV's.
