Remote boot opener

[glynlucas]

Since my car does not have a remote for the central locking, I've made one. I have two remote buttons one to set/unset doors and alarm and another to remotely open the boot. However, I can't figure out how the current boot switch works.
Does anyone know where the relay is for the boot solenoid? The Bible circuit diagram doesn't seem to show the boot switch circuit at all (maybe I'm just blind!)

Thanks for your input guys. I managed to complete the wiring and now have remote locking and remote boot opener. Total cost £35.00 using standard parts from Maplin electronics.
