hello guys! how to connect a type A doorlock system?
correct me if im wrong.
the R/S unit has a (-) negative lock/unlock output right? and the vehicle has a positive output (+). how can i connect the wire?
do i need to use Two relays in order to convert the positive output to become a negative output?
87 & 85 - ground ?
86 - to vehicle (+) lock/unlock ?
30 - to R/S unit lock/unlock output ?
thanks ------------- tianot

R/S output lock to 85.
12V+ Constant via a 2amp fuse (shared with other relay) to 86 and 87
30 to vehicle lock wire.
Repeat for unlock.
Diode across each relay 1N4004, from 85 to 86, band towards 86.

No, just go to the relay section, this question and your multiple errors in the first post make me want to suggest read the relay and diode sections on this site or have it done professionally.
