2011 tacoma, viper 4103, pkall

Just connect the Viper lock/unlock wires to your factory arm/disarm wires and change the unlock programming to "double pulse". The Ground when running wire will need to go to 2 different places and must be diode isolated (band towards viper). First it will go to the ground when running input (may also be called status input) of the PKALL. Second it will connect to the keysense wire. This 2nd connection will disarm your factory alarm during remote start. Alternatively, if you will not be connecting the rear defrost output then you can connect your ground when running to the bypass and the defrost / 2nd status output to the keysense. Just make sure that the 2nd status out/defogger output is programmed to "2nd Status"Kenny

Okay, that makes more sense now but just to be perfectly clear the ground while running wire will still need to be diode isolated regardless correct? Thanks again so much!

Some people do, but I never have. Its up to you. But if you use just the status out (ground when running) for both then yes it has to be diode isolated.Kenny

Thanks again, I REALLY appreciate all the help!

if people are confused; what kenny is saying if the status is used as GWR for 2 or more modules, which utilize the same function, then there is no need to diode isolate them, since there is only one purpose. if you connect a bypass module and a keysense circuit, diode isolation is required. This is because they are 2 different circuits, with 2 different features. maybe this clears it up for some.Ted

Yea, thats a better way of saying it. I was trying to figure out the best way of stating it but couldn't think of the easiest way... haha. Thanks Ted!Kenny

I hope I didn't bite off more than I can chew with this project. I have made 90% of my connections all soldered but now I'm having a brain freeze as to what the tx/rcv data wires go at the ignition switch. Oh boy, this is not like I remember it seemed a lot easier 20 years ago! lol

Depending on if you have a "G" key affects how the PK-ALL is installed. Look at the shaft of the key directly next to the plastic head and you will see either a "G" (G key) or a dot (non G key). The install guide for the PK-ALL should list your TX/RX wires by pin number. They are usually tough to test so in many cases you have to just pay close attention that you get the correct wires. PK-ALL Install Guide (G Key) PK-ALL Install Guide (Non G Key) Look in the pictorial discussions area and you'll see a 2010 Tacoma I did not that long ago. I believe I have the RX/TX wires pointed out fairly clearly. If you have the "G" key (which you probably do) the install is different than mine and you will have to follow the above install guide. 2010 Tacoma PictorialKenny

Thanks again to all, SUCCESS!

Out of curiosity, did you have the G key or the standard key? And if you were happy with your experience on this site, please donate to the site here to help keep everything up and running! Kenny
