Ive searched everywhere for more information on alarm wiring for my Celica...I have partially installed a TLD alarm system (Chinese breed)...Everything going except central locking...There is a blue wire from the brain marked negative door trigger I have not found a home for this! Also a blue/black wire labled negative window trigger again need a home for this..It also has a purple wire labelled trunk release but pretty sure theres no such switch in the car.......There are two wires also from the brain which I have spliced to the lock(blue/black) and unlock(blue) as per installation.......Last one engine disabler where would be the easiest place to tie this wire into, its come with a relay etc and the installation recommends the HT coil, any thoughts.....Many thanks
