OK Guys, this is the story as to why I went to Tyree Harris and if I disapoint someone...that is NOT my problem.
I ordered the specified wiring harnes for my 1928 early 1929 Tudor Sedan from Brattons back in 2011. Completely forgot that I did as it was in a box I had stuffed away. About a year ago 2014, I called Sacramento Vintage Ford and placed an order telling them it was for the Tudor and that I had the original terminals for which I was going to use and they sent it to me.
Fast forward to now, 2015, I discovered the one I got from Brattons so now I had two Wiring Harness for my 1928-early 1929 Tudor Sedan with single bulb headlights.
About June of this year, I decided to compair the two...well guess what, they were different from each other.
So then I ordered the specific drawings from the Ford Archives pertaining to this particular era of production.
The drawings that I received from the archives were for A-14403-B Headlamp Wiring Assembly and A-14405-B Stop and Tail Lamp Wiring Assembly and A-14401 Wiring Assembly on Cowl.
These drawings are very specific and very detailed. The drawing dates were February 1928 and the next drawing date was January 1929 when the Two-light system was going to take the place of the Single-bulb system and nothing inbetwen.
So now I decided to do some comparisons between Brattons, Sacramento Vintage Ford and the original Ford drawings of the harnesses themselves.
Brattons harness problems were as such:
The Stop and Tail Lamp Wiring Assembly, A-14405-B…From where the two green wires go to the Stop Light Switch and continuing toward the tail light, that distance on your harness is 61 inches plus the 1 inch of exposed wires to attach to the rear tail light. HOWEVER…The February 27, 1928 Part Drawing shows a distance of 84 inches plus 1 inch of exposed wires (Part Drawing enclosed). Other than that, all other distances appear to be correct. This means that one has to attach an extra 23 inches to get to the required 84 inches and that is not correct on a restored to original Model A of this time period. (Review page 440 of the March 1930 Ford Service Bulletin).
The Headlamp Wiring Assembly, A-14403-B…The problem here starts at 15-1/2 inches (not including the exposed wires to the contact plate) to where the two wires take off for the right headlamp. That length is two inches longer, not including the 5 inches of exposed wires, on yours as compared to the drawing (Part Drawing enclosed). This is also explained in the MARC/MAFCA RG’s and JS’s.
Where the separation is, and according to the part drawing, there should be three more inches of “Black Glazed Cotton Braid” on the wires leading to the left headlamp, the two horn wires and the cutout wires. This is also explained in the MARC/MAFCA RG’s and JS’s.
Also, when I compared the “hookup” to the contact plate or light switch on your harness, the hookup, appears to be wrong…I looked and looked at it and it is just not right…maybe I am not seeing the hookup right but according to the schematic drawing of the hookup in the January 1928 Ford Service Bulletin…it is different.
The Wiring Assembly On Cowl, A-14401…The one I received from you has a 18-1/2 inch Black Cotton Braid with a single silver spiral thread going from one end to the other which should not be there. Also the red wire that attaches to the ignition switch is 5-1/2 inches. This should be 4 inches. Also on this assembly, you have a yellow wire with a single black tracer…This should be a double black tracer, not a single black tracer. (Part Drawing enclosed).
Sacramento Vintage Ford harness problems were:
The Stop and Tail Lamp Wiring Assembly, A-14405-B…(Part Drawing enclosed). This assembly that you sent me is perfect, length wise, however there is just one thing wrong with it…It is made with 14 gauge wire. It is supposed to be made with 16 gauge wire.
When I started to try to put the original flag terminals on to the wire itself, they would not fit. The wire, being 14 gauge, is just to big where the 16 gauge does fit the terminals. Really bummed me out.
The Headlamp Wiring Assembly, A-14403-B…(Part Drawing enclosed). Here again, the wire is 14 gauge where it should be 16 gauge. The first segment, starting with the Black Glazed Cotton Braid, on your wire is 12 inches. This should be 15-1/2 inches. The remaining wires were made long enough to cut and put original terminals on but can’t because the wire needs to be 16 gauge. The braided area for the two yellow wires to the cutout is 12-1/2 inches instead of the 10-1/4 inches on the drawing.
I informed both companies of the problem in a letter, provided copies of the drawings and the data in the MARC/MAFCA Restoration Guidelines and Judging Standards to back up my concerns to see if they would do me up one that was correct according to the Ford drawings.
Did not hear back from Sacramento Vintage Ford but did Brattons and the fellow there told me that he would have to talk with Walt. Still no answer.
I then contacted Mr. Harris, explained the situation to him, and he said that he would make me up what I requested according to the drawings and that is just what he did and I am very pleased.
So if you want something done right, do the research, get the drawings from the archives, and request your Model A vendor to do it right the first time. Good God, you pay enough for these things...they should do it right from the start. Maybe the later 1929-31's are done correctly...I do not know. All I know is that this time period was not done correctly with Brattons and SVF.
