Can anyone tell me which wire goes where on a 2wd amal valve. Just doing the finishing touches to my restoration and noticed one of the previous owner has cut the wires for the amal valve. Obviously must have been running manual boost controller. Or a quick photo would be appreciated

Also, im assuming I have the correct wires, black/red & yellow/brown ?? and they seem to come from the injector/dash temp sensor part of the loom??

thanks in advance
