One thing to remember about this harness and most others, they usually do not supply any of the extra ground wiring needed. So remember to include them in your harness runs before taping up your harness.
Dash and interior lighting, and the door switches are usually negative triggers.
So the harness will may supply power to a bulb, but the other side maybe a cable run to a door switch or dash with which then grounds when the circuit is closed.
This is also true of things like the horn button which is a ground trigger.
understood. luckily for me...ground is not far away on this car being the whole dash is metal and connects to the body, chassis, etc. I have used my test lamp a couple of times and just grounded to one of the openings in the dash. worked great. so things like the dash lights will ground via the socket right to the dash and only power is a single wire to the bottom of the bulb. the dome light is the same way.
now on the 55 there are some double pole light sockets that I will have to run grounds for. the 37 is much more simple, even though my head is killing me. I am hoping all this I'm learning on the 37 prepares me for the 55.
the headlights being converted to 3 pole H4....there is a separate hidden ground wire, but the rest of the wiring in the engine bay wont really need any ground wires. the brake lights ground to the bulb socket.
but you are right....I've already had to take apart things I've dressed up because I had to get to a wire. so I'm not going to be dressing up anything until I'm really sure I'm done.
I know my mind is making this harder then it really is. that snooze really helped.
the reason I'm not going to use the horn relay on the harness is that Packard pushed the ground through the column to the inside of the engine bay and this harness has the ground wire for the horn relay under the dash. I could use it, but I'd have to splice in and run all the wires myself to the engine bay and I have a perfectly good horn harness already that will take me about 2 seconds to hook up.
