1939 1940 1941 firewall wiring kidney shaped cover
 

Here are three different firewall wiring covers. The one on left is the commonly seen 1939-1940 cover. I believe the center picture is the 1941 cover with the wide openings for harness. The one on right has a flat top and i believe it is an early part for 1939. Has anyone seen one of these flat top covers or know anything about it? All three have identical positions for screws. Does anyone

Larry, The flat one is early '39. However, I can no longer recall when the design change occurred. It was very early - that much I recall. It was done as you would suspect, to allow more room for the wires.

The Early Ford V8 Clubs 1938 - 39 Ford Book page 4-31 states the part was revised 0n 10/28/38.

I wonder HOW the 39 Mercury's missed using them???

Re: 1939 1940 1941 firewall wiring kidney shaped cover
 

Can anyone confirm that the center one is in fact 1941 and maybe 1942. Someone with an original car might be able to check for me. Thanks......40larry

It might be 41 42 Ford Truck not passenger car cover. See attached 41 Ford Mercury has only two wire openings for passenger cars part number 11A-14600. 1942 - 47 has larger wire openings than the 41 Ford and is part number 21A-14600. Hope this helps.

The center one looks more like the one on my 41 1/2 ton pickup. Although mine is smooth on the top and does not have that indent by the top wire opening.

Early 39 Mercury had the same problem as early 39 Ford. The Mercury wire cover part number was 99A-14600.

Re: 1939 1940 1941 firewall wiring kidney shaped cover
 

That still leaves the center one in my photo without a clear answer. it has all three large wire openings.

Re: 1939 1940 1941 firewall wiring kidney shaped cover
 

Can someone confirm that the center one in my picture is the 21A-14600 that is called out for all 42-48 passenger cars. Does the 21A-14600 have two or three wire openings?




thanks 40larry

This is my 10/38 production, 39 Mercury and it has NO part you speak of????? OR at least in any of these pictures!!!! NOTE my above post as 39 Mercury NOT having one!!!!

Not sure IF it helps you Larry but this is the only shot I have of my 46 Tudor I had and the part you ask of......Looks like two!!!!

A closer scan

Re: 1939 1940 1941 firewall wiring kidney shaped cover
 

See attached the cover pictured is off of a 1942 - 47 Ford Pickup.

Re: 1939 1940 1941 firewall wiring kidney shaped cover
 

Thanks. That seems to answer the question. Your picture is same as my center cover pictured. It appears that the 21A cover only has two wire openings. So my center cover is the 1942 to 1947 pickup. If this cover fits the 42 to 47 pickup should there be a 21C-14600 listed in the parts book? Have you seen a 21C part number for a cover in any Ford parts book.

The parts book calls out the 99A-14600 as used on the 1939 and 1940 Mercury.

Re: 1939 1940 1941 firewall wiring kidney shaped cover
 

40 Larry I have attached a photo of all the cover styles I have at the moment so you can compare the differences. I do not have a 21A-14600 right now but it had only two wire holes and was correct for Ford and Mercury.

Rockfla if you look at the firewall on the engine compartment side below the voltage regulator where the wire harness from under the dash connects to the wire harness for the engine compartment you will see three small holes for the screws that hold the wire harness cover. I have had at least six 39 - 40 Mercury covers and all have had only two holes for the wire harness. Two of the covers were early and the balance later. Looking at all the covers you will see all have the same location for the screws. Hope this helps.
