Help needed sorting this electrical mess

The lunk heads having previously owned this 73 Tii should be incarcerated. This is just the latest of a slew of really incompetent work...much of it coming out of Select Classics is no surprise.  Can those of you with underdash electrical experience weigh in on what is being accomplished in these photos or what may be the reason for this fubar? It appears that the mess of yellow wire is  intended to bypass the Molex-type connector...???  Would anyone be able to photo what the original harness looks like on either side of the connector?

Hard to tell until you take off the black tape but it looks like the Molex connector is from the wiper switch.  Intermittent wipers, perhaps?  There is an easier way to do that by swapping out the relay from a later car but I don't know if a '73 would support that.

 

I feel for you - this is as ugly and ham-handed as it gets.  When I got my car, there was a similar mess.  I ended up ripping out all of the add-ins, which allowed me to make sense of the wiring.  Fortunately, original wire is easy to identify so anything that did not look like it, had to go.

WOW,

  well that looks to be the wiring for the right side

column switch. it is possible that the previous "parts changer"

used a part from a CS or Bavaria. also it is possible that

the car has had an intermittent wiring done to the wiper

system. not real familiar with the conversion. so that said,

the end not wrapped is supposed to mount in the hole in the

rusty column bracket and a female plug containing male

prong would push into it. it looks bad but if it all works

properly and the connections are soldered, i would let it

go until you have concerns. find good used column

replacement parts and then do a full change over to

eliminate that when or if it fails. i have the body side wiring

if you need that too.

To see if the previous ham-fist owner added jury rigged intermittent wipers, the quick way to check is to see if the wiper relay has seven terminals vs six.  If you need the wiring diagram for adding intermittent wipers to a '72 or '73 with the turn signal stalk PM me as I re-created the original factory wiring on my '73 around 1987 and it's been working fine ever since...

 

Remember that the right side steering column stalk on a '73 governs turn signals, wiper on/off, wash/wipe, and on-street parking lights when the ignition is off...  that's a lotta wires.

Hmmm. Well, I confess that I wired a Bavaria wiper delay circuit into my 2000CS many moons ago. Now I can't say as I recognize any of the wires in the picture but I could scan my wiring diagram if that would help.

OMG....lol

This is clearly the work of Derelict Classics "mechanics"

If you are not planning on stripping that crap out, take a look under the chewed up insulation tape where spliced to the factory wiring. I suspect you will find wires just twisted together and taped.

all of the above indeed. Yes it is the right side stalk on the column. I have the Prospero's Garage schematic and will eventually get it right ( he says optimistically) ...it just takes so freaking long for an old guy laid out under the dash. Like Healey, I'll be ripping it all apart.... I just hope the idiot left enough of the leads to make a proper repair. I was hoping that somebody might have a photo of what that Molex looks like originally . Thanks guys

So, mystery solved thanks to some help from people in the know at Vintage Sports Restoration. The car is a 73 tii . The switches that came with the car were the later variety and had to be rewired to connect to the original harness. A new set of early switches on the list.

What is all that rust behind the steering column and what looks like the interior side of the firewall? Never seen rust there before. Must be from leaky windshield??? But it looks bad and I would address that before it gets worse.

Or a leaking heater core or heater box seal.

I am splitting this into several replies to drop the photo size/content.

Wow.  I hope these help.

I had considered going to the old style stalks with the turn signal on the right, but I couldn't work out all the connector changes.

Attached is a file I created with some of the connectors identified, but not the turn stalks.
