Firewall grommet for temp and oil lines

[Joe Flanagan]

I'm trying to figure out where in my firewall the temp sensor line and the oil pressure gauge line pass through. Somehow lost track in all the activity over the years. I've looked at various people's engine bays on the forum and they all seem a little different from mine. Here is a picture of my firewall:

Seems to me that the hole for the temp sensor line would have to be a big one since you have to be able to pass the ether bulb through it.

Joe the grommets are usually split. That big round one does the wiring harness and I think speedo cable. On my 48 the oil temp throttle and choke cables all go through the 4 small holes on that oval shaped one. The speedo cable also goes through that one.

[Joe Flanagan]

Thanks Ed. I think I might actually have this drawn out somewhere in a diagram. I'll have to see if I can find it tomorrow. I think you are right, though, that temp and oil both go through the oval grommet.

[Frank Elder]

Joe, I know it is not the same but my wiring went through the oval. Car is covered in snow or I would see if the others go through there too.

Oil/speedo and temp go in the oval aluminum wrapped grommet.

OK, thank you everyone. Frankie, no need to go out for my sake. Heck I only just today dug a path to my garage.

I just found a reference photo I took of a 49 Deluxe at a salvage yard:

Anybody know what that third line coming through the oval grommet is?

[Niel Hoback]

Wiper line?

[Young Ed]

Speedo cable

Everytime I check my car I see this guy, it must be winter or I need some relief....Stand up guy:)Every body needs a Joe Flanagan, that is......you keep the rest of us going.

So tell us about Rodney and the snake, or cow ,or whatever..I'm sure he did a karate on some junkyard knucklehead......

3rd line is the speedo cable

You simply take out the two bolts holding the aluminim frame, open up

one end (kind of like opening a clam), and then you'll see the rubber

part inside it is split down the middle. Just open it up, put it around

the lines once pulling them thru the hole in the firewall. Get things

all lined up, close the frame, and re-bolt to firewall.

[BobT-47P15]

All sortsa things come thru that middle grommet..........

Choke, throttle, and speedo cables.

Temp gauge, oil pressure line

Plus a black wire to either a horn or the siren.

Interesting that they turned the oval grommet 90 degrees on the '50...

Here's mine (reload if the pic doesn't show...)

Mine has the temp, oil, speedo, and OD cable.

Here's another shot, I have the E-brake cable coming out of one of the round grommets in the corner.

Man I really like the look of your motor!

[Joe Flanagan]

Pete, I have the e-brake cable coming out of the same spot. I do have one tiny rubber grommet above and to the right of the big oval one. It accomodates one wire. Any idea which one that might be?

[p24-1953]

i wonder why they quit using those grommits, my 53 has these hard plastic(rubber) round ones that break if you try to do anything with them,

Is it the one right above the regulator in your pic? My '50 doesn't have a hole there... might have been something added by a previous owner?

Here's a pic of my firewall just after I pulled the engine. (reload for the pic)

I was trying to remember what came out of the second round grommet above the ebrake cable, and it was the armored wire to the ignition switch. I got rid of the armored wire and re-wired the switch under the dash into my fuse block.

Pete,

Whatever that little single wire grommet is, it's original.

On the upper right of your firewall you have one big round grommet and two smaller ones above it. Which one of those two did the armored ignition wire come out of?

Joe-

The large round grommet is for the wire harness. The smaller one above it on the right is the ebrake cable. The small one on the left was the ignition armored wire.

[Joe Flanagan]

Thanks, Pete. Now I'm all ready to go.

The grommet location in WWll day's,

The car is an original one that did see combat.
