Does anyone have any pics of a vacuum diagram for a 420a? There is a hard line that comes from the throttle body, and then there is the triple vacuum source nipple thing on the back of the manifold.

Also, on the cruise control vacuum box (black box under manifold) there are (2) outlets. Which one goes to the cruise solenoid and which one goes to the manifold. Can you cap any of them and just not use them? I took the EGR off so I know that I could cap that one. Could I cap off the cruise since I don't use it anyways without causing problems?

Any help is appreciated!

BTW, I did search in case anyone was wondering. : )

Ok, I tried searching a little more and come up with this link:

Dino said that he doesn't have emissions. How do you remove it on a 420a/where is it located? I know that it will probably throw a CEL, but that really don't matter.

If this was a 4g63 I wouldn't have to ask, but I haven't messed with my 420a a lot because it's my daily driver.

Again, any help is appreciated greatly.

I have three hoses on the triple nipple on the manifold.

1) EGR (blocked off)

2) Cruise Control (blocked off)

3) Unknown (I can't tell where it runs too)

I reconnected the EVAP vacuum line, but this mysterious hose has me puzzled.

Any input?
