Hello,
Anyone have the wiring diagram for a 2018 Toyota Rav4 for remote start/alarm install. The trim is xle. Going to be installing a compustar with blade-AL.
Thank you

Does the RAV4 XLE have Push to Start? Some did if equipped with a "Extra Value Package".
Either way, most of the wiring info you need is included in the BLADE-AL install guide,
use TL-6 for PTS vehicles and TL-9 for H-Key vehicles.

Soldering is fun!

Yes, this one does have push to start. I was not aware of the different key options on the xle. It's not my car by the way. Yes, I do have the install guide for blade and already flashed the proper firmware and bypass for the car. I'm looking for additional wiring like the defroster and just to have another verification of the wiring on the vehicle.

I have found that the iDatalink install guides are extremely accurate. The Blade-AL gives you
most everything. You can find additional install info in the iDataStart HC3452A install guide
for your car.
This Fortin Install guide will give you color photos and locations for the wiring also :

If you are installing an alarm system, you probably won't need the Horn wire but here it is :
Horn LT GREEN (-) DASH FUSE BOX WHITE 56 PIN CONN, PIN 39 *
The guide lists the (-) Parking Light wire but here that is :
Parking Lamp (-) WHITE (-) HEADLIGHT SWITCH or AT BODY ECU WHITE 30 PIN CONN, PIN 30 *
The guide also lists the AutoHeadlight wire if you want to disable that during a remote start.
Here is the (+) Parking Light if you wanted to go that route :
Parking Lamp (+) GREEN (+) DASH FUSE BOX WHITE 40 PIN CONN, PIN 38 *
And finally the Rear Defroster wire :
Rear Defrost BLACK (+ LATCHED) DASH FUSE BOX WHITE 56 PIN CONN, PIN 1 *
You will need a relay for this wire, it is high current and (+).
I believe most of these * wires are the same on your 2018 as in this Pictorial on a 2013 RAV4. Just
note that the 2013 XLE was an H Key ignition system, not a PTS vehicle so the ignition wires are
different so follow the Blade-AL w/TL6 install guide. Here is a link to that Pictorial :
