I'm intalling a viper 350hv in a Yaris 2010 4 doors. I know that the door trigers are independent and know that have to use 1 amp diodes. I bought a bag of 25 rectifier diodes and they have diferent numbers in them : im4001, im4002, im4004, im4007. Is there a diference between those numbers? Will they work? The rectifier diodes are the corect ones for this kind of job?

Should be fine.

The 1N400x series is/are 1A diodes.
The last digit is its voltage rating - 4 for 400V & 7 for 1000V being the common ones these days. IN4001 is 50V, and IN4002 is 100V or 200V.

IE - the lowest voltage rating is 50V which means the diode can withstand 50V in the reverse direction. (The will handle 1A in a forward direction; typically with a 0,6V drop.)

BTW - I assume you meant 1N.... not 1m? (That should be trivial anyhow - the key is the 400x number; it's probably some foreign printing machine that m instead of n, and changes inductors to resistors (L to R). posted_image

Totally unnecessary on a Yaris if it does the following:-
If your dome light stays on for about a minute after closing the door but shuts down almost immediately when you lock the door, go to the negative switching wire on the dome light for all your door contacts. This also does dome supervision so you won't need that either.
For your indicators, try a neg feed on the different wires at the hazard switch, that's that done.
most commonly used/available is 1N4004.

Join to blue wire which should be for trunk and hood, use 2 x 1N4004 diodes in a Y shape, with the bans away from the alarm. Actually you only really need one inline with the trunk trigger band away from alarm. I may be wrong but isn't the trunk light tied in with the dome light on this car?
If so the answer to your question is it ain't required. But check for yourself.
