I received my ALP kit yesterday so like any kid with new toys I had to start playing with them immediately.

I had inspiration from some of the other threads of 2014-18 Sierra installs and this is how I did it.
Took about 5 hours +1 bonus hour because one head connector wasn't quite right.
Sorry the engine bay is pretty dusty

Ran sensor wires through the firewall using the grommet on the driver's side right in front of the door

Once all the cables were fished through the front fender to the engine bay I routed them to their respective spots.

Removed the cowl at the front of the engine bay, mounted all the sensors level and connected them to their respective leads.
Some pictures of the routing I used. I used zip ties and 3M tape on some rub points/sharp spots just to be safe.

Inside the truck I have the Hifi speaker and GPS module in the dash under the steering column. All of the wiring is spooled up and tucked away under the dash or near the firewall.

I used a micro2 add a fuse for power and didn't take any pictures under the dash!

Overall it was not too painful to install. Planning to have it tested soon

@Logan T I have 2 Rx and 1 Tx - the Rx are in the bottom slats/Tx right under the M! I used your thread for some inspiration :)

Ah I see from that one pic it looks really good! I think that will perform really well. That's the best place for the TX it also makes it look clean and blended in as best as possible. If that doesn't perform well you can just move the RX sensors either to the same slat as the TX or one above like mine but I think that will do well. Hopefully you can find someone with Dragon and you'll know for sure how covered you are.

Yeah I hear there might be a dragon tester or two floating around in AB - hopefully I can track one down!

Nicely done. Looks like an easy install in comparison with some cars!

Ended up adding some rears as the local speed camera enforcement is actually a Truspeed S out the back of a pickup truck. I also travel to Edmonton on occasion/Hwy 2.
Haven't had the rear tested yet - hopefully someone in the Edmonton area can hook me up or @Tripleturbo once he's feeling better!
24 inch radius goes to about the top corner of the tail light from bubbles, overlap on plate - the RX may be a tad too close together.
Truck needs a wash.

Nicely done. Only issue would be snow haha.
Yeah snow definitely can block them pretty easily, I also have to consider snow/dirt build up on longer drives in the winter depending on road conditions.
I've yet to actually have a legit hit :(

I think I’m 13.5 “ from the center of the TX to the inside edge of the RX on both sides for the rears.

It was shot with a DETC and was JTG front and back. I shot it myself as well.
Yeah mine is definitely a little more spread out than yours. I expect it will perform pretty well. I gotta find someone with a DETC! :p

Great looking install! I only wish the back of my Boss 302 was that easy! The rears will be my next project.

Here's an update on my setup:
2TX/2RX front setup to be tested this weekend.

For the rear I now have a 3D printed bracket, which is modified from @wrxsti15's bracket:
I've attached the .stl file for the bracket, it had to be reinforced on the holes with some glued on washers to prevent cracking. The angle is slightly downward (maybe 0.5-1 degree) when mounted but there's a couple of things that can be done to level it out. This tested pretty well against the DETC. If I can I want to pull the TX into the bracket a little bit to make it look a little more subtle. TX is held in place in this bracket with sugru on the back side. Note that my truck is stock height so a level or lift will negatively affect the angle of this bracket. The rear RX sensors were pulled towards center mass quite a bit from the prior posts and improved testing. I'll get some new photos on the weekend.
