almost sorted my new wiring harness install.

Edited as ive fixed things today:...

Ive got power, lights, hazards, brake and reverse lights all working. YaY! The monster is waking up! However I have a problem.

This is a 1978 car with a period-correct harness. I have had best luck so far with the Haynes manual: diagram 15-1979 special onward seems to match all my wiring colors. Anyway, I have all four indicator lights working and blinking with the hazard rocker switch. But I have no turn indications. Left or right, not one indicator lights up when I power the car and work the indicator stalk on the column. The stalk positions worked last time it was driven before disassembly. This system has a single relay unit bracket built in. And I have a weird leftover. There is a single wire, green with I think orange tracer line on it...could be brown but its old-going from the indicator stalk socket and its supposed to connect to something. its loose and touching it to a leftover pin does nothing...Ive tried to bridge some pins but no results.

Im missing something I know.

ideas?
I'm almost there! When I solve the electricity issue I will drop in the 1098.

The Blue/White and Blue/Red wires are the headlight low/high beam lines.  Green/Red and Green/White are Left and Right turn signals (from the switch to the lights).  The Light-Green/Brown line is the feed to the turn signal switch.

thank you for all of that. So that feed to the turn signal switch.....where does it connect? because I can't find any pictures showing the actual unit from behind.

Im considering just buying a replacement stalk unit to match the replaced wiper stalk and thereby eliminating any problems that may be inherent.

I took some pictures of the wiring connections under my Mini's dash (a 1983 Panel Van) as well as some showing the turn signal and wiper switch stalks.

Picture #21 shows the connectors under the dash.  There are three coming down the steering column on mine: one for the ignition switch, one for the turn signals/horn/hi-low beams, and the third for the wiper/washer switch.

Pictures #22, #23, and #25 show the turn signal and wiper stalks for style reference.

In picture #21, the ignition connector is behind the other two and hard to see.  It has brown, white, and white/red wires.  Of the two foreground connectors, the larger one with the variety of blue and purple wires is the harness from the turn signal switch.  The smaller (bottom) foreground connector with mostly green wires is from the wiper/washer switch.

The feed to the turn signal switch should be coming from the hazard switch.  You should have two flasher relays, one for the hazards and one for the turn signals.  They are on separate circuits.  The signals only work with the ignition switch on and the hazards always work.  There should be another light-green/brown wire going from the signal flasher to the hazard switch.

It's common for the hazard switches to cause problems and they're a bit fragile.

In the "off" position, the hazard switch connects the signal flasher relay to the turn signal stalk so the stalk switch can send the "flashing" to the right or left signal lights.

In the "on" position, the hazard switch disconnects the signal flasher relay and connects the left and right signal signal lights to the hazard flasher.

I appreciate the pictures. The location of the wire and where it goes that I was trying to find is not in the sockets, but behind the switch where they connect there, behind the stalk. Either way, I found the solution....

Ok, so i solved the problem. It turns out that not only is finding out what wires exist but its hard to find reference to everything between on the diagrams, specifically relays. Im glad I had some pictures of my old shell before I stripped it all down to really see not just how things were put together and where, but what I didn't know I have on this one.  It's also easy to mislabel wires. I indeed had suspicious extra wires and on a whim I put the relay on those....ta-dah. but....I had to re-connect the feed wire to the stalk.

So I tore apart an old socket from the old wrecked wiper stalk, and got a pin female connector out of it, with wire, that I cut and soldered onto the loose wire, heat shrinked all my work and the thing perfectly fit onto the pin on the back of the signal stalk. Now I just need a second relay from the store tomorrow and its all ready to close after surgery...but before that, its interior time.

So now carpet, and dash lower padding, and then after adding more relays for front fogs I can finish the whole buttoning up and get to engine stuff.
