As you see in the enclosed pic, my car had some adapted horns attached to the firewall, (one hole over the patent plate!). The adapted horns worked with one wire only, therefore I am guessing that ground was through the bracket, to the body. I already got the correct horns and restored them, and they got two cables. How are these cables supposed to connect? Is it one current, comming from a relay, and one ground? Where to? 2. My horn relay is also on the firewall, in the driver's side, just under the adapted horn. Where is it supposed to go? 3. My car also had a starter solenoid in the firewall which you will see in the pic. Where is this one supposed to go?

Hopefully there are two unused wires there and the color codes should match with the wires from the horns. There is no relay. Power (-) from the battery goes directly to the horns, the second wire runs to the light switch through the center contact to the bottom of the horn rod up the rod and when the horn button is pushed the top of the rod is grounded (+) 37RAGTOPMAN 02-02-2011 @ 6:36 AM reply profile send p.m. Senior Posts: 1958 Joined: Oct 2009 I would think the extra horns were installed because of a defect in the wiring, I would look for the horn wire coming out of the loom at the bottom, of the light switch at bottom of the steering box, if not rewire the car, if you want it original, that starter solinod was first used in 1937., 36 FORDS had a floor mounted foot push button, so that also is not original, but if you are happy with it leave it alone, I think if you get a wiring diagram, it will show you to a certain point, what should be there, I think it is time to get a few books on the subject,this way you will only have to do it once, my cents, 37 RAGTOPMAN, jerry.grayson 02-02-2011 @ 7:55 AM reply profile send p.m. New Member Posts: 128 Joined: Oct 2009 What are you trying to accomplish, correct 1936 parts or good driver? If you are going to original, the entire wiring harness is incorect, the carburetor is wrong year, the fuel pump is incorrect, and several other items. If you want to just have a good driver, then the above items are O K. Then why change the horn? 36 conv sedan 02-02-2011 @ 8:35 AM reply profile send p.m. Member Posts: 50 Joined: Dec 2009 What am I trying to accomplish? Good question, but a simple answer is: first of all, a good driver, as it is right now, and then, to gradually be improving it till someday it will be basically correct. I already got a set of correct '36 horns and restored them, so they will be going on today. I already removed the extra horns, and I will be removing the horn relay also, and look for the wires as you suggest. I did buy a correct 1936 wiring harness but rewired (without adapting the harness itself) to make horns work. I will also remove the starter relay, as it does have the floor switch between clutch and brake pedals. I will get to carb and the rest later, which I did not even know it wasn't correct. What I know is not correct, and probably will not be for a good while, is that I have cast iron heads, but I have heard so much about the aluminum heads (and I have had a few problems with a Packard) that I am inclined to leave them on, just painted to simulate aluminum. Basic intention is to have a good driver that would look as correct as possible, but never a show car. Thanks, victor 36 conv sedan 03-15-2011 @ 6:22 PM reply profile send p.m. Member Posts: 50 Joined: Dec 2009 After realizing I had many things wrong, I decided to do the car correctly. I already found the aluminum manifold, a good aluminum head plus a cracked head with looks like it could be repaired. I still need to find the oil scoop and the 97 carburator. I took the engine out to clean out everything and paint. Is the Ford engine paint supposed to be a very dark green? The authenticity manual I understand says that all the cast parts in the engine were painted, but not the machined parts... and I believe some machined parts would be visible if not painted, like the surroundings of the intake manifold, between it and the heads. Any ideas? The radiator, it mentions, got painted in a special heat conductive paint, apprently flat, but it is not clear to me if I should paint it flat black or satin. Any ideas?

The other option is to remove them and have them aluminum sprayed so they look authentic. As a personal opinion I think the aluminum heads are more trouble than they are worth. They definitely cause electrolysis and if you ever need to take them off they have a tendency to "grow' to the block.JMHO TomO 03-16-2011 @ 7:07 AM reply profile send p.m. Senior Posts: 7250 Joined: Oct 2009 The machined parts are visible when the engine is assembled. I used a high temperature clear coat to make it easier to keep those pieces clean and rust free. Use the satin finish. I agree with Tom about the heads. You will need to be religious about your anti-freeze and rust inhibitor and may still get some electrolysis.

I know Wurth has an Aluminum spray, apparently with lots of real aluminum content. I could also have some epoxic paint made, to match the actual looks. Any ideas? I get the idea on the engine green paint and the clear machined surfaces... great tip. Thanks, Victor
