Lion C803 Car Alarm

I need the circuit diagram for the circuit board and wiring diagram for this alarm. Any help would be appreciated. Numbers on the board are: C803D No:040716 and WD1246H. The cpu/firmware is: c004fOnly the Best will do

i was also needing help with this as im a novice at setting these up but shrug i managed it all myself am i able to post pics on here? cause ive redrawn the wiring diagram i got as i think the original drawing was done by a pre schoolerIve got grey knews for you its niether good nor bad.

Hello Mercury2006... That sounds great. I would love to have a copy. I actually got the factory in China to email me a copy and you are right, it is an awful drawing, very hard to follow. I am sure they must have some machine to do all the chinese/english transaltions too. Would it be possible to email it? Only the Best will do

im not sure where to email it but i got the manual email to me but i also have my own diagram i think i can help u both but im strugglig with the siren on mine its got 4 wires and when i conect the red to the main unit (brain) and the black to ground and leave the blue and white out it just sorta clicks doesnt chirp properlyIve got grey knews for you its niether good nor bad.

From recall, with the battery backup siren, you connect the black to the car's negative, and red to car's positive. The blue and white cables seem to be the +ve and -ve triggers for the siren. I'm pretty sure you can connect the alarm output to either of these, though one might be louder My email address is crazy_grandpa_society@hotmail.com Cheers, Harold
