Hi, does anyone have a diagram of the vacuum hose that goes from the trunk to the release button? Thanks in advance

 

I've seen trunk release mechanisms from other years and they look and function pretty much the same. This is a diagram from 1959.
The hose entering the trunk going to the opener and is clipped along the frame between the bumper, then follows along the frame rail going from the back of the car to the front tucked up along the floor pans, then enters the engine compartment between the firewall and the wheel well on the driver's side, then goes through a grommet on the firewall and enters into the dash board, then enters the glovebox and finally connects to the switch in the glovebox. The other vacuum line in the glovebox (provides the vacuum) goes through a grommet on the firewall into the engine compartment and connects to a vacuum storage tank/can, and the other nipple on the tank/can connects to a vacuum line.

 

That's an installation drawing, which is what I think the OP wants. A diagram would have a block for the port on the manifold, a line to the block meaning reservoir, then a line to the block meaning switch, then a line to the block meaning actuator.

The issue is that drawing is for big cars.

On the A body, it routes from the actuator in the decklid, back to the right side hinge, across the package tray, down the back of the seat, under a sheet metal protector for the right rear side footwell and I believe it goes under the front seat and along the edge of the carpet on the right side. Up the kick panel behind the glove box to the switch which is typically up high and left, then through the firewall to the vacuum car, then to a T in the control vacuum for the AC, on the engine side of its vacuum can.

 

From the 69 CSM.


Sorry no pic for the actuator in the trunk.

 

I pulled one from a '68 Cutlass many years ago and this is how it was routed. It is now installed on my '69 4-4-2 convertible.

The hose from the switch in the glove box goes down under the carpet and low along the passenger side of the hump, back to the rear seat. At the rear seat, it routs slightly more to the passenger side. As it goes under the back seat, it fits under a formed metal protective piece that is fastened to the floorboard with screws. The hose then goes up behind the passenger side rear seat back and into the trunk where a 2 clips hold it to the outer side of the passenger side trunk lid hinge. From there, it is routed through a slot into the trunk lid on the forward passenger side just aft of the trunk lid hinge (not the round hole but a smaller slot to the outside of the round hole) and then emerges through the opening next to the vacuum mechanism where it connects. Kind of hard to describe, but I hope this helps.

The connection to a vacuum source under the hood depends upon the options your car has.

What's funny is I thought it was neat to add this little option, but I never use it! I'm so used to using the key to open the trunk that I never think of that little button in the glove box!

Thank you Randy that helps a lot. I will try this on Sunday.

 

Thanks Koda

 

Thank you all, I will post pics

 

This is all the parts in the system.
Note the metal channel and clips

 

Hi thanks. I have everything except those 3 tabs. I just need to know where the channel goes on the floor and the 3 tabs. That would give me an idea on how to route the vacuum hose.

 

You will see the matching channel stamped in the floorboard where the long hold-down bracket follows the same contour. If my memory serves there are dimples where the screws go. The three tabs I'll have to look through my AIM.

This was removed before cell phones had cameras. I think the tab application was obvious, and there were dimples for them as well—two on the front floor and one on the rear. I think one tab was on the 45° firewall up by the heater core.

Again, you will see the routing by the channels on the floor.

I seem to remember the 68 vert this assembly was removed from; the vacuum canister was in the A/C car location on the firewall, not over by the brake booster...the vert did not have A/C. But the diagram above is for 88/98s. I'll have to look at the AIM to see if an A/C car has one or two of the vac canisters.

This is a good thread, as I'm thinking it's time to install mine.
