2003 celicia gt remote start problem

The above link is a diagram to help you isolate your toyota ignition wire .  On the diagram above, your "ON" wire (from the SPY remote starter brain) is the "WHITE" wire connected to terminal 86.  You will use this SAME "ON" wire to similarly trigger a SECOND relay for the second ignition wire on the Celica.  Please note, the second ignition wire does NOT need to be isolated:

Second relay connections:

85: chassis ground

86: "ON" wire from spy r/s brain

87: 12 volts fused

30: connect to second ignition wire on celica directly (no cutting of the second ignition wire necessary).

So, the "ON" wire will trigger BOTH relays .. therefore a "Y" connection will be made with this "ON" wire to both relay's terminal 86.

Are you sure there isn't a ground while running wire off the r/s brain?

Also please note: the diagram in the link above presumes your "ON" wire has a (-) negative output.  If it is a 12v+ (positive) output, then for the isolated ignition wire #1, connect terminal 85 to chassis ground and connect terminal 87 to 12 fused volts, and connect 86 to the "ON" output wire.
