This must have been answered before, but multiple searches have failed to give me the answer. This is in regards to a 1970 FJ40. There is a vacuum switching valve on the left front fender that is cylindrical in shape. There are four (4) small diameter vacuum lines coming out the side (circled in blue in the photo). Mine are all hooked up, but I do not know if they are hooked up to the proper place. There is one orphan vacuum nipple on the carburetor (circled in red). I am uncertain which line, if any should be hooked up there. I believe the schematic WASvisible on a sticker which is on the VSV, however the sticker has long faded into illegible / unreadable. So far I have been unable to find a schematic for this VSV. I did find the attached page somewhere (I forgot where), but I am having trouble applying it to my VSV. Can anyone point me in the right direction? Is there a pdf of the 1970 Emissions Manual available? (I have not been able to find one yet). Thanks for any input!
