Need Some Help

I am getting ready to install a new wiring harness and would like to get some pictures of the firewall showing the wiring harness and how it is routed.  I have pictures of Ted's car and I would like to get some other examples so that I can pin down exactly how it looked originally.   Any help would be appreciated.

Have been short on time this week, if you need any details let me know. The white wire with the speedo cable was (is) my temporary fuel pump power. Ignore. Followed YNZ's setup for the most part. They have power for the clum fed from the horn, that is why there are 2 green wires. (I know its the wrong horn) If anyone has an extra right one they want to part with let me know.

Horn looks like a correct Klaxon 12C to me.

Thanks Dave for all the photos. 

I have noticed some difference in how the harness was run across the firewall from another example vs. Dave's.  I would greatly appreciate another photo showing the firewall of a car with original wiring.  Just looking for a consensus especially on the visible wiring in the engine compartment.  I know I am splitting hairs but I only want to do this once.  I have a pretty good idea just need conformation.

Tks, Chet...

That one is an 8C, buy off of some random guy at a tractor show. It serves the purpose for now...

Ted,

I have pictures of your engine compartment.  The problem that I am facing is in addition to the regular wiring, I had Yn-Z add wiring for a 7 wire flasher system.  This adds 5 additional wires coming out of the firewall's main harness.  The end of this harness mates up with the harness going to the front lights as well as the harness going to the rear lights.  All this in the area of the steering wheel switch assembly.  I will have to locate the main harness to mate with the other two and have the wiring for the horn go to the horn from the steering wheel switch rather the other way around.  I think this is pretty much how my car was when I stripped all this out.

I am sure that Dave's picture is truly original but the Yn-Z harness with the additional wiring doesn't work with that bracket.  Probably wouldn't have been a problem if I didn't have the 5 additional wires.  I think a minor deviation from original for the safety that is added by the flasher system.  After all I like driving my cars and having the flashers is definitely a plus.  I am using bumper mounted fog lights for the front flashers and removable rear bumper lights for the back. 

It should come out nice without having to mount an additional rear tail light.  Wing nuts on the rear bumper lights and off they come and the car's rear single light will work as designed.

Do you have a flasher system, installed in your car ?

I do not...when my Dad had the car re-done in the mid-80's, it was kept original as he found the car in 1962.  Nothing was added to modernize and everything on the car is 100% stock/original as we know it.  The only changes that were made was he changed the body color (originally a yellow/tan color - I have some old pics) and the addition of an 6v electric fuel pump.  Some day I'd like to rebuild/fix the vacuum tank, or at least get the plumbing right for looks and still use the electric pump.

Hay Ted,

I have the same issue with the vacuum fuel pump in that when my car was running it was using an electric pump.  My vacuum canister has two pin holes in the bottom which I need to solder and hopefully get it working again.  I restored/preserved it a number of years ago but never made it functional.  Maybe soon...

I believe Tod Fitch mentioned that some guys leave the electric pump in the fuel line and use it to prime the vacuum pump if needed.  I just don't remember if that was with these vacuum pumps or the regular mechanical pump in the PA/PB.  I was thinking of doing this on my boat just in case the mechanical pump goes south I could switch over to the electric pump in an emergency.  Of course more projects then time to work on and get done.

My '29 Ply coupe has this flat wire strain relief from out from the head. FYI

Plymouth and inovation go hand in hand.

Rich,

That is the way the original harness was run, I believe this bracket is original and correct for your car and mine.  I just don't happen to have this bracket or if I do, I don't remember removing it.  Possible, maybe having a senior moment.  In my case I am not sure how I will handle this since I am dealing with 5 additional wires for signal flashers.   At this time using this bracket doesn't seem practical for me.  The new harness would be better positioned down the firewall in the direction of the steering column.  Here it would tie into the front light harness and the rear light harness.  Wire connections would be hidden by the frame.  There is always some minor trade off for safety additions.  Not there yet, the engine is still in the shop so its another thing to ponder.

I can show a possible alternative once my car is home.
