Big Jeep - '88 Grand Wagoneer: AMC 360, 6-7" of lift, TF727, NP242, Howell FI, 3.31 gears, Dana 44's front and rear, 32" BFGs, ...
Little Jeep - rescued/resurrected '51 CJ3A with a Ford V8, CJ2A window, 2.5" Rancho lift, 31" Super Swampers, CJ7 Dana 30 front axle, ...
I've got a weird combo of vehicles/parts that I'm trying to merge into one, so please bear with me.
1. My rig has a Ford 260 V8 engine, a universal 12 circuit wiring harness, and a Signal Stat 900 turn signal device (the one with seven wires).
2. I'm using the stock CJ3a headlight switch with the two settings/options, parking lights or all.
3. I'm using a CJ5 dual filament parking light from Omix-Ada and Walck's Naco Standard CJ2a tail lights (the one with a red wire and a black wire out the back).

I'm trying to figure out how to have the parking lights go on with the headlight switch but still flash with the Signal Stat. I figured I'd run power to the headlight switch, from that switch to the Signsl Stat, and then from the Signal Stat to the parking lights. BUT I can see how to feed power from the headlight switch to the Signal Stat.

I'm also not sure if the red and black wires to the Naco replicas are both hot forthe two different filaments (and so the ground is through the brake light case to the tub) or if red is hot and black is ground or ...?

Help!

Thanks,


P.s. - I've got the Signal Stat 900 wiring diagram and have read whatever I could find on this, but the answers I'm needing just aren't out there.

You need to treat them as two different lighting systems
12 volt fused power to the light switch, and a separate 12v fused power to turn signal switch. The turn signal switch feed should go to the flasher on the X terminal terminal L and P should wire up to you turn signal, hopefully your diagram shows this.

If you wire it off the light switch like you originally post. when you lights are off you will lose power to the turn signal switch.

hope this helps you out
 
Yes your bulbs generally ground to chassis at the housing.
 
Thanks, guys. Both responses are helping me conceptualize this circuitry a lot better.

What threw me off was that I come from a world where one wire is hot and the other is ground (electric guitar building), so it just never occurred to me that bolting the light to the tub would ground it. Just to be sure, I'm running a ground wire from one of the mounting bolts of each light housing to the frame.
 
All wired up and working correctly.

For the first time since I bought this proejct in August of '13, I have a street legal and running flattie.

Life is good!

Let's see some pics :chug:
 
Here's one. At first I took a pic on the driveway, but it didn't look in its element, so I drove it up onto my lawn.

I'll start a project thread and throw in some before, during and after pics. It's my first full build, so I'm quite pleased.

The paint job is new, but I distressed it to make the paint match the rumpled tub (it's largely rust free now but a bit like a potato chip). I was able to save all the original sheet metal except for some hat channels and the inner window frame, which is from MD Juan.
 
And has a 260 V8! must be a powerful little jeep! nice. :chug:
 
Nice, like the plate as well.
