2018 Toyota Sienna LE Keypad Install

I am looking to install a keypad on my 2018 Toyota Sienna LE (with key...NOT push button start). The one I have is similar to this one: https://www.amazon.com/Accele-RS505-Numeric-Touchpad-Keyless/dp/B01IDX2EO0/ref=sr_1_4?ie=UTF8&qid=1519403804&sr=8-4&keywords=car+keypad&dpID=41qro0Bp58L&preST=_SY300_QL70_&dpSrc=srch Can anyone help me out with a wiring diagram for my vehicle? I'm thinking I just need POS, NEG, Door Unlock, door lock and alarm disarm wires? There are instructions for the keypad here (not my post, but has a picture of install page). https://www.tacomaworld.com/threads/accele-rs505-keyless-entry-install.347288/ Does anyone know if the 2018 wiring is the same as the 2017 model? Maybe I can refer to 2017 diagram, if I can find one. Thanks for any help! thanks!

Did you ever find out how to do this? I just ordered the same kit.

What exact Year, Make and Model are you planning to install this in?Soldering is fun!

2018 Toyota Sienna LE FWD

I can't find any solid info on the 2018 Sienna but it appears to be similar to the 2017 model in most areas. The following info is good for a 2017 so you must locate, test and verify it on a 2018. As far as I know, the Sienna LE model does not have a Factory Alarm or power Rear Hatch. Constant 12 volts WHITE (140A) DRIVER DASH FUSE BOX WHITE 1 PIN CONN or thick Red @ Ignition Switch Plug, middle pin   * Parking Lamp (+)        GREEN (+)             @ DRIVER DASH FUSE BOX Lock          BLACK (-)        @ BODY ECU WHITE 30 PIN CONN, PIN 9 Unlock      GREEN (-)        @ BODY ECU WHITE 30 PIN CONN, PIN 10 Pwr Sliding Door Left      YELLOW (-)          @ BODY ECU - WHITE 28 PIN CONNECTOR PIN 16 * Pwr Sliding Door Right    VIOLET (-)           @ BODY ECU - WHITE 28 PIN CONN, PIN 18   * * Verified on 2018 model. ADD ON unit wiring. Green/White to Chassis Ground Green/Yellow to (-) Lock Blue/White to Chassis Ground Blue/Yellow to (-) Unlock Black to Chassis Ground Red to either +12V Constant listed above Yellow to (+) Parking Light Purple to Sliding Door Yellow/Black to other Sliding Door Soldering is fun!

This works! You Rock! The only thing I can't figure out is the Parking Lamp. You said: Parking Lamp (+) GREEN (+) @ DRIVER DASH FUSE BOX But, for the life of me, I cannot figure out where that is. I don't see a distinct green wire going into the driver's fuse box. I took a few pics of the area: https://imgur.com/a/vyXtGVw (I also included some snapshots of the EWD for the "Turn Signal and Hazard Warning Light" from TIS for the 2018. Dunno if that helps.)

Most installers use the (-) Parking Light wire. The (-) Parking Light wire is very easy to find at the Headlight switch connector. Your PKE unit only supplies (+) Parking Light outputs but you can get around that if you want. All that is needed is a SPDT relay to convert the (+) Parking Light output to a (-) signal. Here is the info : PARKING LIGHTS ( - )    YELLOW (-)    @ Headlight connector, Pin 18 of 20. Photo of headlight switch plug. You can test for this wire by using a Digital Multi Meter set to 20V DC. Connect the Red lead to +12V constant and connect the Black lead to the suspect Yellow wire. With the switch in the OFF position you will read 0V. With the switch set to Parking Lights you will read +12V. Here is the relay wiring : Relay Pin 86 to either Yellow (+) Parking Light output wire from PKE unit Relay Pin 85 to Chassis Ground Relay Pin 87 to Chassis Ground through 2 amp fuse Relay Pin 30 to Yellow (-) Parking Light wire at Sienna Headlight switch connector Relay Pin 87a - not used - insulate I use mini-relays rated at 10 amps for this type circuit. They can be found on EBay for around $1 but require some soldering to add the needed wires. If you want a mini relay that comes pre-wired, look for a Directed 8616. You can also use the larger 30/40 Amp relays.Soldering is fun!

I'd also be willing to bet that you could get the (-) Parking Lights at the Body ECU. It should be the Yellow wire indicated in your revised photo below : Soldering is fun!

Cool. Thanks! Also, if anyone else is looking at this. Here are the other connections that worked for me

Thanks for sharing. I still have not ordered my keypad. But I'm curious what you needed the 2 sliding door wires for?thanks!
