Safety latch is electrically operated wired though the stock power lock switch & has a manual knob also,throwing a pin forward into a small hole to prevent the door from opening in case of a latch failure!
I know of three cases of BearClaw latches failing causing a lot of body damage with the door ripping back!
Don't think the stock Toyota latches would fail,but rather be safe than sorry!
Lokar makes these!

And just think, I thought my single hinge setup on a single cab was a pita... Very nice work bro! Do you have any more pics of how your running the inside handle etc... Im running mini bear claws on mine. Im planning on somehow keeping stock outside handle just to f*ck with people, even it it just pops the solenoid. I got the pocket all welded in on door #2 now

wow talk about doing things the hard way. The work looks great and its cool to see a good write up on a rarely seen project.

This is the handle lay out,I used a 2nd pulley on the latch side to pull the cable away rubbing & pull it up more in a straight line

Here you can see how the cable end bolts right to the handle 2 the same hole as the plastic rod lock was in

Here you see the safety latch & soleniod position,below the stock latch & to the out side of the door. The soleniod pulls straight down.
Because of the position I had to make a pocket @ the door front to the outside edge for the safety latch pin to enter

Will get finished photo's of this when done today

These are the electrical connectors I'm using

I cant really see your cable picture and the other one didnt load. Where did you get the second pulley from as I was planning on using the Lokar kit as well

E-mail me & I'll send photo's to you! The sizing thing WAS NOT WORKING!
Well send Monday as a busy finishing this project & leaving tomorrow afternoon for Danger Zone !

Right on bro I appreciate it, Whats your email addy, Shit just shoot me a pm, and lemme know where you got the other pulley from? Direct from Lokar? looks like I'll need some extras too the way Im looking at setting mine up

its not a good idea to ground your solenoid (or anything) inside the door. I have fixed many intermittent door poppers by running a ground wire inside the door.
