White wire from ignition switch

Doug,

The white wire connects to the brass connector on the side of the ignition switch housing.  The white wire completes the electrical circuit to ground.

Thank you John but that part I know. It is the connection to other end that I can't find.

There is now more wiring in this thing under the dash then in the space shuttle.

It has the P-E Ignition Switch controller, the Electric Parking Brake controller and push button switch, the push button start on the column, an Electric Power Steering unit with controller box, P-E A/C Controller, P-E Headlight Motor Controller, not to mention power seats, power Vitalloni mirrors, Gentex electric self dimming rear view mirror and EFI, all more or less squeezing in a very small confined space, and that's on this side of the cabin. Don't ask about the passenger side.

Oh, and the early dash was changed out to a Euro fiberglass single pod. So you might begin to understand why my memory is getting a little fuzzy. But I did find that set of keys I couldn't find for my SHO Taurus I lost 15 years ago, so all is not lost. Things are just not progressing with the velocity that I had anticipated.  It really seems self defeating to set a time table on completion dates.

As a former Project Manager, what you do in that case is just keep pushing completion date down the road "due to unforeseen circumstances". That's ok as long as you continue to keep getting a pay check and you don't have to cancel your summer vacation.

So admittedly this is my own fault and at some point obviously I relocated the connection to the main harness. I am NOW labeling everything with a P-touch. I will eventually trace a couple of suspicious unaccounted for wires to the door switch but I was hoping to jar someone's memory and they'd say, "oh yea, that white had a factory splice into the XXXX wire."

So far I just get puzzled "faces" in response.

See diagram attached.

Doug,

The white wire connects to the bullet terminal of the ignition key housing and to one terminal of the door switch.

The other terminal of the door switch has a green wire that connects to the key buzzer.

The other terminal of the key buzzer has a gray wire that is spliced to a red wire that comes from fuse 7.  That red wire also feeds the horn relay and the A/C condenser fan relay.

FWIW:  Bill Taylor's diagram shows an orange wire spliced to the red wire, and I have a photo of a '74 relay panel showing a brown wire instead of gray or orange.

The white wire at the horn/turn/dim switch connects to the red wire at the headlight switch.  Oh no....not another RED wire !!!

There you have it,  more De Tomaso confusion.

John

Thank you John.

Maybe I am not confused? I'm just Detomaso'd?

I understand that it is the '71 harness that has various remnants spliced in? Not the later cars.

You have correctly identified all the colors in my dilemma.

Forest? Where is the brown? Looks like one of those "Rainbow Parades"? Maybe the person who did that assembly was one of those "sissy boys" getting revenge?
