1968 vacuum correct diagram

[MDS]

Good Afternoon

Have both the 67 shop and 68 supplemental shop manual for the thunderbird, neither vacuum diagram seems to be correct for my vehicle. Hopping you can help, both vacuum diagrams show a junction block ( 3 lines) directly behind the L/H cylinder head. mine only has two, one at the lower right hand firewall the other directly below the master cylinder. would you have the correct diagram?

(vin tag 8Y87N143001) Let me know. Thanks. Martin.

Do you have the electrical/vacuum supplemental book?

Do you have the electrical/vacuum supplemental book?

No, did not realize there was, would you have a copy of the under hood vacuum diagram for the 68 with only the two vacuum blocks on the firewall rather than the three? If not no stress, I'll look. Thanks greatly appreciated.

It's an 11" by 17" document so I can't copy it and have it be legible. Not everything is on the same page or even close. You really need the manual.

However I can describe what's there in it. I assume your right/left is based on standing in front of the car.

There is one junction block to the right of the master cylinder. It's labelled as "left junction block" in the manual. This has vacuum lines for the headlight doors, driver side door locks, swing-away steering column, windshield washers and some other functions. This block can change depending on A/C option installed.

There isn't anything I can see as a junction block below the master cylinder. There is what looks like a bracket for vacuum lines there.

There is a center junction block behind the engine. It's small, and appears to be mostly used by the defroster and register.

There is a left junction block labelled as right junction block in the manual. It's behind the left hand cylinder head. It is for door locks, remote trunk lock, and some A/C functions.

Here are some links to the diagram book:
