new wire harness install questions

[tow hook]

i got a new wire harness for my 62 3b there is 3 harness in the box the left and right are in a pretty much hooked up, i will do the rear after i know the front is working a ok.



the left side (driver side ) parking light has a red and black wire. the red wired goes to a yellow wire in the harness. but there is no hook up for the black wire?!   i can take it the power block for the lights,and it lights up. but how would it blink ?


the horn was missing when i got it, i got a free horn that didn't work from a buddy. it's of a early 5  it has tabs . does all the horns have tabs ? the harness i got came with ring terminals


when i do put the rear harness in should i use these to do it with ?

lastly the head lights and parking light work, turn signals do not. i found a flasher in the dash,  it has a red wire that goes no were. were should that be hooked up to ?  and how can i test the flasher it self  with a multi meter ?

 thanks

In my harness, the 16 gauge yellow wire goes to the left front turn signal, the 16 gauge black wire goes to the right front turn signal. These are connected to the left harness separate from the three wire terminal block on the left fender. The three wires on the terminal block are: 16 gauge blue - R & L front parking lights; 12 gauge red - high beam; 14 gauge black - low beam.

All the research I have done says the horn has spade terminals, not ring terminals, I had to change mine.

Red wire from the flasher should go to the accessory terminal on the ignition switch.  You have to put a load on the flasher unit, don't think a multimeter will work, but a 12 volt light bulb will.

Hope this helps

thanks, i finally got pics to up load.

yep mine is hooked up the same way. so my spare driver side parking wire should go to the blue wire on the block?

thanks for the horn info i'll have to find away to change the ends to the horn.

thanks ,, i'll have to put a ring terminal on that wire and move it over to the ign switch and check it.

 thanks for the help

i wish they told you a bit better were one wire met the other. i'm not a electrical guy... so maybe it does in a way. seems odd that i have one wire with out a match. and the rest worked just fine.

I think so. I replaced the wires and sockets in my parking lights and made the wire colors match the ones in the harness.  I tested the lights with a battery first, bright one is turn signal, dim one is parking light.

That's the same horn that I have on my '64.

Maybe these will help, I used them as a check list as I hooked up each wire in the harness.

tonight's work. i put a ring terminal on the flasher red wire, and hooked it too the acc on the ign switch, and put the flasher relay in. i hooked up the 5 column wires to the 5 from the harness ( i tryed to color match the wires from harness to the column ), and no blinky, i had the key to the acc position.      park lights come on as do head light. they do not come on at the same time ?? !!! could i have wired the head light switch wrong ? the hi /low switch does work for the head lights

 from  the flasher  a yellow and black wire  goes up the the steering column (not the same as this). https://www.kaiserwillys.com/media/wysiwyg/Flasher-Diagram-Update.jpg i should wrote down how the wires were matched before .
 I   went and did some checking an saw a new turn signal switch, and had this diagram https://www.kaiserwillys.com/media/wysiwyg/947350-947348-Install-Update_3.pdf  this link shows 7 wires,  my steering column has 5 wires black, red/orange, green, brownish/ black, and green i hooked them up the best i could . ( turn signal harness to column ) front left is yellow to yellow, front right is black to green, left rear is blue to orange, right rear orange to brown, and brakes brown to red.. and still no blinky the new turn signal switch has hazard lights which mine doesn't have..

 any thoughts on either issue ? not sure what to do next ?

tow hook,
Do you know what brand your turn signal switch is?

Chuck mentioned testing the parking/turn signal lights with a connection to a battery.  One wire at a time.  Bright is the turn signal, dim is the parking.  Once you know which wire does what you can add tape to the wire and label what it is.  Color may not help depending on how the sockets were wired.

Your headlights, from your description, sound like they are hooked up correctly.  I also use a wiring harness diagram from the Service Manual.  There you can see which post on the fender is headlight and which is parking.  I had a detailed list and diagram with my harness and I was still writing notes in the margins to keep me straight.

funny you ask, i just went an took a look just before this post. it's a sparton scs-3r and type that into goggle and bam https://www.tapatalk.com/groups/cj3b_bulletin_board/sparton-turn-signal-switch-need-a-little-help-t3142.html

i will try this later weds and try again to wire it up

 as for the parking lights  bright is the turn signal dim is the parking ( not sure i get what you mean by that ) the parking light has two wires a red and a black.

 i did check my service manual section I page 126 and yes one parking light wire goes to the block on the fender.  so that does solve that. so i didn't have it in the right spot yet

 so weds night rewire the turn signals again ( as per the link above ), and move the park light wire so it's lit when the head lights are on

 thanks for the help, i'm not much of a wire guy. shoulda done some more goggling before i started

  The parking lights were not originally wired to be on with the headlights. First notch out on the switch = parking lights and tail lights. Second notch out, headlights and tail lights. When the headlights come on, the parking lights go off. They were like this on most American vehicles until 1968. You can make the parking lights stay on with the headlights if you want to, but that's not the way they were.

... as for the parking lights  bright is the turn signal dim is the parking ( not sure i get what you mean by that ) the parking light has two wires a red and a black....

I want to believe you have a double filament bulb in your parking light socket.  Otherwise the two wires wouldn't make much sense.  That bulb has a big filament and a small filament (just like the tail light).  So, one wire lights the big filament (bright) and the other wire lights the small filament (dim).  The dim wire will connect to the block on the fender so that when you pull out the light switch the parking lights will come on.  Based on which terminal you connect to on the light switch, when the headlights come on, the parking lights go off ( I believe this is original configuration) or if moved to the tail light connection the parking lights will stay on with the headlights.

Added:  What Bruce said above!

Once you mark your parking light wires, you should have an easier time matching the connections to the turn signal wires.

Good work finding the info on your signal switch!!

 um wow ! that's weird, i knew they were optional in the 50/60s, but that seems odd, thanks for the info... i didn't start the rear harness yet. so i'll save that in my head for later when i do the rear. thanks

red wire = bright and black = dim, so i have them in the right spot now.

i got the turn signal switch wired correctly ( did have it right the first time  ), i have no power at the unit on the column ( i took it apart and replaced the small bulb ) and tested for voltage at the flasher. no 12 volts to the flasher, had the key in the acc postion as well, no juice seems odd.

just tested the acc on the ign switch had 12 volts, back probed the red wire to the flasher and had 12 volts.  i herd a loud pop the other night in the garage ( had the harness hooked to the battery ) could smell burntness near the driver fender area, couldn't find the source though....... my guess is that flasher is bad ??

trying to get another flasher local, will update

[tow hook]

got the flasher @ auto zone, and the turn signals are alive !!   cleaned out the dust and dirt  from turn signal box. replaced the bulb in the box ( then checked it has no power ) it may come to life after i hook in the rear harness ?

ready to hook up the dash cluster i have 4 wires, and 3 studs

green from ign switch
white from fuel sender
gray from the coolant temp sensor
purple speedo dash cluster light

https://shop.willysamerica.com/v/vspfiles/assets/images/cluster_id4.jpg

as per the diagram what stud does the dash light go ( purple wire number 9 and 10 on the left side diagram ) ? i see were the bulbs go up top

i put on gloves and put the bulbs in for the dash cluster, and the only bulb that lights is on the gray wire comes on with the key

so that lead me to look for other wires.... and i found a double purple,( looks like it's number 1 on the left side harness ) goes to the ign switch coil term..... on the ign switch i have battery, acc, start, and ign.

 so were is the coil term they speak of ?

thanks again, getting so much closer

Good progress!

I'm hesitant to give advice or opinion on the cluster instrument since I don't have one.  I'd hate it if I suggested something and it cooked a wire inside.  So,  what I've done is suggest reading here:

https://cj3b.info/Siblings/DJDetails/DJ3ASpeedometer.html

https://cj3b.info/Tech/FuelGauge.html

and follow the links to get smart on this instrument. 

Others have jumped in and have done theirs so they may also have input for you.
