how can I add a power lock switch?

[gabriel2012]

Okay so I got a k9 mundial 4 alarm installed on my hb but the doors don't unlock all together when done by hand as they all lock/unlock with the remote(I'm sure its because the shop used 2 wire actuators instead of 5 wire)

so I'm looking for the Oem toyota switch that goes next to the parking brake( I don't know where to buy it, searched google and ebay)

along with instructions on how to install it with my existing power locks

The OEM switch part number is: 84930-52050

You would connect pin 6 to ground, pin 4 to the unlock output of your alarm and pin 5 to the lock output of your alarm.

Yes. The dealer list on it is about $35.

Yaris is regular negative double pulse, not 5 wire, the difference would have been using SPDT relays to make it work, not different actuators.


Based on the symptoms you described, what is the most likely cause is that they tapped in to arm/disarm wires instead of using the lock/unlock wires. When using a DMM, the arm/disarm wires would have displayed the same characteristics as the lock/unlock wires. In the yaris, you can pulse the arm/disarm and it will lock/unlock. The wires need to be moved to the lock/unlock, and need to be programmed for double pulse. Save money on stuff you don't need, and take it back to have them do it properly. In the event that they don't have access to techdocs or directechs, then let me know, and I will send you the proper wiring diagram when I get to work on Monday.

Thanks for your input, basically this alarm has programmable functions. by double pulse you mean press once for driver's door and twice for the rest?

if so the alarm has this programmable feature

edti heres what the manual says

Double Unlock Pulse: (On / •Off) - Configures system to change the single unlock
output pulse into a double pulse. Some vehicles require a double pulse to unlock the doors;
when needed this feature saves the expense of optional parts.


the feature is currently off, do I turn it on?

From your initial post, your actuators are aftermarket, not OEM, so the double pulse doesn't apply.

[gabriel2012]

ah okay thanks scott :headbang:

I'm not quite sure how you got that conclusion, but you're right if he does indeed have aftermarket pdl. (but you already knew that.)

I still think they hooked it up wrong.

And so that you have the knowledge, Gabriel, some locks can use a double pulse, meaning you don't have to push the button twice.

[gabriel2012]

Got it, thanks for the details, right now I only press it once and both doors unlock.

And yes the actuators are not oem since I have a base yaris with power nothing :(
