VCCA Home Forums TECHNICAL - 1945 AND NEWER 1946-1948 Rewiring My 48

Getting there.Chev do you remember if your old harness had spade terminals on it at the headlight switch? Mine did and the new harness came with ring terminals. I called YnZ and they said that is the way their orignal was and so they make them to the original.
One other thing. The dimmer switch in my 48 is the one shown for the 42-47. No problem tho.
Got to run the rear harness tomorrow.

Keith,I will look at these areas tonight.I am pretty sure the headlight terminals are the ring type..I will get back to you.Any thing else while I under there??

Cannot think of anything more.

Chef, you don't need to take a look. Wondered more about the original. They said they build them with the rings on them.

Keith, while looking for something unrelated, I came upon my old headlight switch. I had looked for it when this thread started but could not find it so I figured I had already thrown it away. Anyway, as you can see, mine also had spade terminals, side spades to be exact, all but one. I too was disapointed my Y&Z harness did not match. I also said,"Oh well". This switch also confirmed (what I went by) that 1A goes to the CHG (+) side of the Batt gauge.

Guess you can call YnZ and tell them to "get their act together" it's '47 that has the "rings"...I just checked mine...
Thanks for the post Russell...

I would think it's obvious why they switched to "open spade clips"...It saved time during installation...To bad YnZ doesn't also do the obvious...Call 'em...!

So, YnZ was wrong in their instructions about the 1A...?

I have not checked the YnZ wiring on the switch yet,to check the connecters..I will do so..My harness is at least 10 years old,we will see if it has changed???

Based only on MY experience, yes.

Steeeerike Twooooo...!!! ....just kidding....grin

i checked out my light switch again and even 10 years ago YnZ used only 2 spade type clips.I beleive its on #12 and #D

Keith said Mine too. Must have had alot left over!

Had a scare last night when I started my 48 to put it back in the garage. I have it hot wired and a battery disconnect. I connected the battery and ignition and pulled it in the garage. Looked ahead and the headlights were on. I had hooked up some more wires from the front. I have the headlight switch and ignition switch pulled. I figured it out this morning. When you pull the headlight switch plunger. It pulls it to the lights on position to get it out. Was a relief as I thought maybe I had wired something wrong. Wiring up the taillights tommorrow.

So the headlight "plunger" was pulled out...?

Correct. You have to pull the plunger to get the switch out of the dash. You pull the plunger to the headlight on positon to push the button that releases it.

Oh, that's right...Push in the button to remove the whole shaft...So now the light switch is wired-up...but still out of the dash...And it's turned-on 'till the job's done...

...So now you'll remount the switch and hold the button in, while you push-in the plunger/shaft...? Then the lights go off...

I put the plunger back in today so I could turn the tail lights on and off. Don't have the stop lights working yet as they go through the Signal Stat turn signal switch. Note to others I got new tail lights from Chevs of the 40's. There is a right and left. I didn't catch it when I ordered them so got the same one for both sides. I drilled a hole for the stud and it works fine. Interesting, the Filling Station only shows one tail light.

I emailed YnZ about this, but haven't heard back yet.
For the dome light, the wires are to short. My terminals are at the rear of the dome light. The harness appears to work with a terminal at the front and one at the rear. I will probaly just make some extensions. Only about 4 or 5 inches.

Does anyone have a diagram or list of what wires to to the terminals on the 3 position ignition switch? I didn't get all of mine listed.

That is odd...Wonder if they thought you were ordering for a '48 Truck...They only had but one tail-light...But a car..?

Ignition switch I can't help you with...I think mine might had come out of a "truck"...

We both have Signal Stat 900's...It appears to me that we'd run the Gray ( right ) and the Black ( left ) all the way back to the lights...I'm looking at my diagram...Okay, there is a wire to the stop-light switch but I don't get it...Is that to interrupt the brake light while allowing the signal to flash...? I've been wondering how that works...

The stop switch is where the turn signal gets its power. And where it splits to each individual stop light. I ran two more wires for the brake lights. I just now thought that I could have spliced into the ones in my new harness. O well it's done now. Going to start another thread about my turn signal.

Ok...I didn't even think about the power...And I don't see it on my diagram...

Keith, about the dome light, check to see if you have any slack under the dash that you may be able to pull out. I did. About the ignition switch. Back up two pages and look at Chef's fine pictures, the two bottom pictures show that only two terminals are used. The bottom/middle is the power or ground, "K" I believe. The right, as seen from the back becomes hot when switched ON. I believe. #13 the coil wire, #5 to DS gas gauge and some of the accessories that become hot when the ignitions switch is ON.

Thanks ruscar. Have to remember to go back and look at the previous posts. Haven't looked about the dome light yet.

Looks like the dome light harness will work by pulling back and taking off the tape. Of course I sliced of of my fingers cutting off the tape. Sure fun getting old and klutzy. Figured out the ignition switch. When I disconnected it from the coil it was on the PS terminal. Looks like the power is on the middle bottom and the PS and DS are the same. Energized when the key is turned to the vertcal or run postition.
Cannot tell about the gas gage yet as I have to drain and drop it to hook up the new wire.
