Hello all,

I have an '88 V12 with Lucas ignition. Does anyone know exactly how the solenoid vacuum valve (2) between the intake manifold and vacuum regulator for the vacuum advance is supposed to be connected? I'm finding conflicting diagrams as far as the vacuum line connections go (i.e. the sticker on my car vs the one on the AJ6 Engineering website).

Also, if I'm understanding the wiring diagram correctly, the solenoid receives 12 volts on both leads except for the first 45 seconds (North America Emission) where one of the leads is grounded? And this is also how the supplementary air valve is operated since it's on the same circuit?
