Remote Start DIY Wiring Guide 2006-2010 Yaris

[tmontague]

Just tried to start the car. As soon as key goes to start a click is heard and all power dies. Only way to get power back on is to disconnect , battery and then the same thing will happen again.

Here is a summary of what wires I connected to what:

H1/1 Red- connected to male bottom terminal in under dash fuse panel (the viper module is receiving power) so this wire is good
H1/2 blue- not connected
H1/3 black/white- connected to ground (works as dome light turn on/off w/ keyless unlock)
H1/4 black/white -connected to pink wire in 4K connected in underdash panel (works as dome light turns on/off with keyless unlock)
H1/5 green/black -connected to brown lock wire on CTScotts guide (works because the keyless fob locks the doors)
H1/6 white/black- not connected
H1/7 violoet/black- connected to ground (works because lock function works on fob
H1/8 blue/black- connected to green unlock wire on CTScotts guide (works because unlock function works on fob)
H1/9 violet- connected to ground
H1/10 white- connected to parking light (-)flask white wire in CTScott's guide on the headlight switch connector
H1/11 black- connected to ground
H1/12 brown - connected to black horn wire in CTScott's guide
H1/13 -not connected
H1/14 -not connected
H1/15 Yellow- connected to the white ignition accessory wire in CTScott's guide (I disconnected it and the car still shuts off all power when you try and start it as I thought maybe this wire was the culprit)
H1/16 -not connected
H1/17 -not connected
H1/16 - not connected

only have the lock and unlock function working as well as the dome light (goes on for 1 min when car is unlocked using fob)

parking lights do not flash and horn doesn't beep when locked 2x. Horn works when pressing the steering wheel button.

When panic is pushed I can hear the relay in the viper module trying to set off the horns but the relay under the hood isn't triggered.

When the car is turned to start a click is heard and all power is shut off from the car. It stays this way until the ecu is reset by unplugging the negative battery terminal. This seems to be an immobilizer issue that is doing this.

If anyone sees an issue with my wiring or sees that I wired to a wrong wire please let me know. I'm out of town for a few days but am hoping to have the car up and running when I get back.
Any help is appreciated...

Correct

Correct

H1/10 white- connected to parking light (-)flask white wire in CTScott's guide on the headlight switch connector
Correct if the wire in pin 10 (4th from the right in that same row) is white/black. If it is green, then you have to use the + parking light flash

H1/11 black- connected to ground
Correct

H1/12 brown - connected to black horn wire in CTScott's guide
See my note in my response above about the correct connector

H1/13 -not connected
Correct

H1/14 -not connected
Correct

H1/15 Yellow- connected to the white ignition accessory wire in CTScott's guide (I disconnected it and the car still shuts off all power when you try and start it as I thought maybe this wire was the culprit)
Incorrect - This is an ignition input to the keyless entry system that has to stay hot even during cranking. This should be connected to the pink wire on the ignition switch connector, not the white accessory wire, which drops when cranking

H1/16 -not connected
Correct

H1/17 -not connected
Correct

H1/16 - not connected
Correct
