Compustar CS4900-S / CM900 Installation Guide | 2000 Toyota Tundra

Hey Everyone!

Just wanted to make a guide on getting a CM900 (Or Cs4900-S Kit) installed in my new-to-me first gen 2000 tundra, first things first I am in no way a professional installer for these kits just a DIY'er with a curiosity for learning so any tips or advice is encouraged (Note this is in Canadian Pesos AKA CAD taken from 8/24/2024, my local shops typically will charge roughly 500-600 bucks for something roughly the same as this)





Before you do this yourself make sure you know what you are getting into, basic wiring tools and basic knowledge on tapping into OEM wires are a must and note this is only for the keyless entry (unlock and locking) and auto start CM900S, NOT the security system aka units with a CM900AS (which have door inputs/start kill switches added on)

Lets start now!

As other users have mentioned this video is a good general starter of installation of these units



Disassembly of lower dash starts between the 5 Min mark till 6 min - Fairly straight forward stuff

I'll be posting the rest of the installation tomorrow or next week (wanting to make it look pretty and easy to read )

In the mean-time here are some resources I will be referring to in said installation if you would like to read through them

Alrighty we are back

Once the lower dash and drivers kicker panel is removed (Follow the same video as previously mentioned, fairly straight forward, make sure to go easy old plastic isn't as flexible nowadays lol)

Now we get into the fun stuff, wiring!, there are 2 main sections CN1 (Main Harness) and CN3 (Unlock/Lock features + Auxiliary Options), additionally please make note if your truck has a factory alarm, you will need BLADE-AL (typically ranges from 60-100 CAD or 40 - 70 USD) (This will be CN2) which won't be covered in this guide, though should point you in the right direction if where to tap in.



CN1- Main Harness Connection

See below for details and picture of the connector location/connector, for splicing, all I did strip back the wires and wrap the new CM-900 wires onto them, and soldered the connections to keep them from bouncing around, once done I wrapped them up in electrical tape and will be putting some tesa tape 51608 to make it nice and neat

1 Red (+) 12V Output -> White Ignition Lock Connector (REQ)
2 Green/White (+) Parking Light Output -> Green Drivers Kick Panel (REQ)
3 Red/White (+) 12V Output -> White/Red Ignition Lock Connector (REQ)
4 White (+) Accessory -> Blue/Red Ignition Lock Connector (REQ)
5 Blue (+) Selectable by Jumper -> Black/Yellow Ignition Lock Connector (REQ)
6 Yellow (+) 12V Starter -> Green/Black Ignition Lock Connector (REQ)
7 Green (+) 12V Ignition -> Black/Red Ignition Lock Connector (REQ)
8 Black (+) Ground Chassis Ground









As for the two other wires location on where I put these will be seen in the splicing of CN3
Green/White (+) Parking Light Output
Black (+) Ground
These will be seen in the next section on splicing
CN3 (Unlock/Lock features + Auxiliary Options)

 

CN3 - (Unlock/Lock features + Auxiliary Options) Connection

In case if these pictures somehow disappear in the future see, physical text of where to connect

1 Green/White (-) Parking Light Output -> N/A
2 Blue / Green(-) Lock Output -> Green/Black Drivers Kick Panel* (REQ)
3 Blue (-) Unlock Output -> Red/Yellow Drivers Kick Panel* (REQ)
4 Black (-) Status Output -> N/A
5 Orange (-) Rearm Output -> N/A
6 Orange/White (-) Disarm Output -> N/A
7 White (-) Horn Output -> N/A Connect to Horn
8 Gray/Black (-) Hood Pin Input -> N/A Connect to supplied hood pin
9 Light Blue/White (+) Foot Brake Input -> Green/White Drivers Kick Panel* (REQ)
10 Red/White (-) Trigger Starter Input -> N/A
11 Red (+) Trigger Starter Input -> N/A
12 Yellow/Black Tach/alt Sensing Input -> N/A






So that is it! once you plug in the antenna you are good to go!,

Make sure everything works properly, by testing both unlock and lock features and additionally trying the auto start, you should be able to start the truck and pushing the brake pedal will cut it off, if no key is in the ignition in the ON position

One issue I have currently is that AutoStart is iffy, sometimes it cranks over / other times it cranks but does not crank over (Possibly setting cranking times) Any tips would help a bunch!




And to say it again the CM900S is merely keyless entry and AutoStart / basic theft deterrent (LED blue light + (Horn if bought)/ If you want something that can protect your vehicle better CM900AS Or kits that specifically say Security and have the CM900AS brain, are the ones which have a ignition setup that only cranks over if authorized by the remote/brain I can still start my truck even if I lock the vehicle

Hope this helps anyone looking at doing this themselves and let me know if there is any feedback or questions on this setup,

Hopefully sometime soon I will make it look nice and neat and show you all the final setup

Connected it and all seem to work.
Lock/Unlock/RemoteStart.
But that's it.
It says that it has some arm/alarm features, but I don't see it. I did connect the Horn and was expecting it at least go into panic mode if the door is opened without unlocking, but it is not.
I don't get it.

Did anybody achieved anything regarding this?
