I search already and came up with 12volt.com. I was going to used this https://www.directwholesale.net/diag...ms.asp?link=DW diagram from this website but the website is down now. I am in the middle of the installation and I am stuck. 12volt.com was helpful but it was still missing some info.

these are the wires I am stuck with. what ever information you have will be greatly apppreciated.

1) tach wire
2) factory disarm (is it necessary?)
3) xxxxxx
4) xxxxxx
5) factory alarm module

I have a 1998 es300. I am installing scytek galaxy 5000rs series. I decide to try this remote start alarm system because it have the ability to be program with a laptop or a pda running windows mobile5. thanks

 

to find the tach I used one of the negative coil wire off the igniter. I am not 100% sure if this is correct, but the remote start works ok, and it don't grind the starter.
I disregard the alarm arm and disarm wires. I did not unplug my factory alarm module. I leave the factory key fob remote at home. I also install window roll up and down module to the alarm. everything works ok.

I install the galaxy 5000rs made by scytek. I bought this alarm because I wanted to try a different brand system. I choose this brand because it have the ability to be program by a laptop or pda. I bought the c-net software and hardware. the c-net came with a serial cable, but my desktop, laptop and my pda don't have serial port. I had to order a usb to serial port adapter.

When you use the remote to open the trunk it does not automatically deactivate the shock sensor, so when I close the trunk it will trigger the shock sensor.

the scytek window module come with a built in temperature sensor that will crack the window when the interior become very hot. I was watching my car in the driveway while it was raining. when the rain stop the sun came out and raise the interior temperature causing the window to crack(vent). This happens less than a hour after the rain stop. I think that was too close.
If my car had ventshade it would be ok but you can't install ventshade on the es300. Scytek told me if I don't want the automatic venting, I shoud open up the module and cut the temperature sensor which is a blue vertical disc. I will do that when I am installing my second module to control the back window.
all of my previous install was prestige alarm system
