Re: windows and locks and poppers oh my
I have not seen any kit that includes power windows, door poppers, trunk release and a remote system but then again I've never looked as most of the time you want to get the best you can in each area and I kinda wonder if anyone really does.
Electric-life would be a company to look at to replace your crank regulators with power models as these are more heavier duty than a lot of the aftermarket kits that use cable type drives. The cheaper ones are also made to work on the more modern thinner and easier to lift door glass. Also the better designed ones will bolt into existing holes and should require less drilling.
For door poppers if you properly engineer the installation and it's attaching points to the stock latch assembly you should not have to get the mongo 50lb pulls that can more easily damage things and force things to work. If it's installed properly then you should be able to get by with the less amount of force actuators/solenoids and have less strain on the latch mechanism. Also when adding door solenoids, run a seperate ground from either the ground wire on the solenoid or from it's mounting hardware into the interior of the car. Do not rely on getting a good ground inside the door structure (same for the solenoid for the trunk).
I would see if you can find a factory trunk release assembly for your car to make installation easier. Most added trunk releases rely on cables to attach to the trunk latch and then you have to drill a hole in the latch release arm and then mount the solenoid elsewhere on the inside of the trunk. The factory releases I have seen only require a hole to be drilled in the trunk latch assembly and then an arm off of the solenoid trips open the latch. they also use the existing latch mounting bolts to hold it into place.
If you want all of this to work off a remote get a name brand and while I doubt any of the systems will wire directly to the things you are adding they will require relays or modules and whoever wires it, make sure they seperately fuse things and have good solid grounds.
For safety, do not disable the inside door release handle and mechanism. Should the system fail or the battery fail with you in it, you need a mechanical way to open up the door to get out. I would also add some hidden switches on the outside of the car so you can still get in should the battery in the remote fail.
