How thick was the two sided foam tape you used? Cap seems quite thick with lots of ridges. Cap underside near cab.
Alu-Cab and the Alu-Cab experts at OK4WD recommend SikaFlex to seal those up underneath. I received a tube with mine but decided against it. If I was running a camper I'd have done it but for the canopy I wasn't too concerned and still no leaks or dust issues.
I guess that's up to you on how in depth of an install you want to get into. Some people are removing their caps to better adhere them too since they can come loose but with the canopy on that's not an issue. Like I mentioned I didn't do that on mine and haven't had any issues yet. If I do have issues later I'll consider it but only being a canopy and not a camper setup I'm not too worried if I get a few drips coming in.
Where did you find that T harness at? I have been trying to find one for my alu cab, and haven’t had any luck.Just a couple quick install notes that might help others...
If you have an Alu-Cab Contour canopy on your 4th gen, and you're a taller person like I am, I thought I'd share an easy solution to the low hanging lift gate, when open. I bought the canopy straight through OK4WD, the US importer in New Jersey. I bought it through Chuck and worked also with Jon, their Alu-Cab expert to work out a few adjustments. These guys are awesome!
The factory rear gas struts are a little short for me and leave the rear gate opening far less than the side panels. I'm 6'6" so that was less than ideal for me. Jon sent me a set of longer struts but they wound up being a touch too long to cycle to full close. We then tried these extenders and that's the ticket! I have them doubled up on each side, they are metric in thread and length, but added about 1-3/16" in total length to the struts and that extra length transferred to 5 inches more on gate height. The gate started out at 71" from the garage floor as it was from the factory, and now it opens to it's max at 76.5", which might be a little high for some but is perfect for me.
For the third brake light wiring, I actually sourced the SmartCap T harness, that would normally come with a SmartCap canopy, that plugs into the 7-way trailer connector under the truck. You simply disconnect the backside of the trailer plug harness and run this T harness in series with the trailer wiring circuit. I then routed the 2-wire pigtail up through the passenger side taillight housing area and drilled a hole in the steel vertical bed support just ahead of the taillight. I then wired on a Deutsch connector on both ends for the connection. The Alu-Cab just came with an open 2-wire pigtail that you can install whatever connection you want. The SmartCap harness comes with a Toyota/Lexus based connector that I cut off in favor of the ones I have on hand. Sourcing the matching connector proved to be a hassle and costly in area. Maybe they're more readily available in South Africa where all this is made...?
I still have to build and install the interior light harness for the 3 LED light fixtures. Rather than tap into the bed side lights like some do, I'll be running to the battery direct and installing a toggle switch inside the rear gate area to turn them on from the rear. I'm shopping products for that setup.
Hopefully the info is helpful for some
one.
