I wasn't very concerned about security because we garage both cars except when they are in use--so purchased a cable kit from Amazon the last time I needed to add a few bucks to qualify for free shipping.
With a tight-fitting faucet washer, zip tie, and polyurethane glue, I installed a stop on the cable sheath.
I drilled a hole through the inner finder liner--a bit lower would be better to clear the latch bracket, but it's a little difficult to tap a center punch back in there, so this was it. I did better on the wagon.
Finished up by crimping a loop, then tucked the thing up underneath, and zip tied this end of the sheath to make sure it would stay put, out of sight and harms way.
It's very easy to release the hood with this setup. I had originally thought of doing one for the passenger side latch also, but they seem to have a much lower failure rate, probably because it is an almost straight pull across the front of the car.
About 1/2 hour per car is reasonable completion for those younger and faster than I am.
