remote start, 95 lexus es300

Its been a while since i don't anything like this so getting everything i need in place before i do a remote start again. Remove my Python 990XP from my old car a few years ago and now wanting to put in new car a 95' Lexus ES300.

So On the H3 harness it requires 3 12v inputs (3,6,8) but yet looking at the wiring diagram on this site shows 1 constant which is white. But another site shows 2 constants ( i will verify once under. Question is can i just bundle all 3 to the one constant? I thought i took a picture of the the ignition from the old car when i took it out but i guess i missed it.

According to the diagram:
12V is white
I1 is B/Y
I2 is B/O
Acc is P/B

Directwire states you have 2 -
white and WHITE/ red

Omega states it has only one -
White

If you only have one, it should provide enough power for your entire install. In that case, it's fine to connect all 3 to the one white wire. If you do in fact have 2 power wires, white and WHITE/ red, I would connect 2 power wires from the Python system to the thicker gauge power wire in the Lexus and the 3rd power wire to the other. Hope that made sense.

Well i got it. It had 2 constant 12v one was white and other was white and red.

Im just taking my time on doing this little by little. This fat kid was not designed to have his body twisted in so many ways. Giving my self a few days to this.

I did get the heavy gauge satellite harness connected and started the car liek normal and all good. Now to test the remote start side of it when i get the tach wire ran.

So right now im under the dash of my 95 Lexus ES300 and trying too hook up the door trigger. All the diagrams i can find shows RED / White at bottom of fuse box 6pin. Well the bottom of my fuse box is a 16 pin and the only RED / white wire shows 12volt with or with out door open.

Any help?

Here is info from Omega:
Dome Light  GREEN/ RED OR RED / WHITE (-)  AT FUSE BLOCK IN DR. KICK PANEL
Here is info from Ready Remote :
Door Trigger  RED / White   -  bottom of fusebox, Located in a White plug.
Here is info from Bulldog security :
DOOR TRIGGER   RED / WHITE (-)    @ 6-PIN PLUG, BOTTOM OF FUSEBOX

Perhaps you found the correct wire are are testing it incorrectly?  It is a (-) signal and should be
tested as follows : Set DMM to 20V DC, connect Red test lead to +12V constant, connect Black
lead to suspect wire.  DMM should go to +12V when door is opened.

Soldering is fun!

sweet fround it it was a green red on the plug for the fuse.

Now can you tell me for the Truck release? Seems like the nnly wires that are correct were for the ignition. I have the 2 Red Blue wires they both show - when i hit the cars trunk release but when i wire it it does nothing on both. So i take a guess one is the factory disarm as from what i understand when i hit the trunk on the car it disables the factory alarm when i hit the button until trunk is open

Looks like you have several options with the Trunk Release.  Be aware that some are (-) and one is (+).  This info
is from Omega :
Trunk Release  BLUE / YELLOW (-)  AT MAIN TRUNK RELEASE SWITCH *
* RED (-) Wire At Trunk Release Switch On Driver Door Or BLUE (+) At Alarm/ Door Lock ECU Behind Passenger Dash
Can Also Be Used For Trunk Release.

While you didn't mention what you are installing, most units have (-) Trunk Release Output and a (-) Alarm
Disarm Output.  Think the easiest way is to use the Blue / YELLOW wire at the main trunk release switch and
connect the units Disarm wire to the RED / Blue wire shown below :
OEM Alarm Disarm    RED / BLUE (-)    DOORLOCK ECU BEHIND PASS. DASH
or this wire ( info from Ready Remote )  :
To disarm without unlocking, give a negative pulse to the smaller gauge RED / blue wire in the drivers kick panel.

So i got everything wired up did a few test runs and all went great. Then went to show it off to a friend and it failed.

Everything kicks on and start kicks in but get a no start
I can start the car fine with the key and I can remote start it with it running so i can leave the car with out turning it off. But if i try to start it from a power down just sits and cranks.

Car is a 95 Lexus Es30. Tried to find a tach wire and got one that went up and down with voltage with revs but could get get the alarm to learn the tach so when it tried to start it would not. I sat there for 2min trying to get it to learn to no avail. So i ended up going in to the menu and turning engine check and off. And this is how i ran it 3-5 times while test everything and it worked but now nothing. Fuses and wires all check out.

What else could i check?
