Hello and thank you for this forum.
I'm looking for a vacuum diagram for an 89 Bronco w/ 5.0.
The 5 plastic lines that come around the back of the right head have been cut and had rubber line put on them. They are not going to the right places. I know this because the smog shop said two of them were giving the wrong type of vacuum signal. The EGR line has constant vacuum and they say it shouldn't.

Can anyone help me find a color coded diagram? Even if it's b&w I'll figure it out. Color would just make it easier.

The 5 lines are colored as follows;
Red X2
Blue
Green
Pink or Tan

Thanks in advance for any help.
Larry

 

Does anybody have ANY ideas where I can get some help with this? Please!

 

A Chilton or Haynes manual should have what you need. You can get them at any autparts stores for about $16.

 

I already checked those. The chilton doesn't have the diagram for the 89 in it.

 

Do you have the engine calibration number? There are approximately 20 different diagrams.

 

Where do I find that calibration #?

 

Here ya go

The engine calibration code is located on an engine information label, which is located on the front of the engine. The calibration number is necessary to identify the correct vacuum diagram.

 

Thank you. I need to have my daughter bring it back over to find out if that sticker is still there. I'll let you know.

 

It will be a number similar to the following
7-54E-R11
The letters and numbers will vary, but it should be there.

 

Well, there is a sticker on the top of the valve cover, but it's been wiped off and it's just a blank decal now.
Any other suggestions?
