I removed the dash from my 68 Cutlass S Convert. Some wire connectors were disconnected , does anyone now were I can get a diagram with pictures of connectors for the interior.
thanks Bruce

 

If you send me a PM with your email address I'll send you a high rez scan in jpg and PDF.

The wiring diagram will show you where all the color wires go but you won't find connector pictures or diagrams anywhere. If, after you've looked at the wiring diagram, you still have questions you're going to have to take pics of the wires in question and post them.

 

This info is in the Chassis Service Manual and Fisher Body Manual.

 

Actually, most of the body connectors' layouts are shown around the edges of the schematic in the Chassis Service Manual.

Also, each connector only fits one thing, generally.
The wire/cable length and form will guide you to the proper item.
The only trouble I could see would be if say the flasher were removed from the harness, and you did not know what went there or where the flasher resides under the dash.

Watch for loose/ broken pins on the gage pods. Much easier to fix with the dash/ gages out.

I have found that a good way to deal with this is to install/ remove the IP [Instrument Panel] as an ASSEMBLY with the wiring all the way to the fusebox all attached. Only a few external things then need attention- park brake wire, under-seat rear feed, and courtesy lights.

 

True, they are on page 12-6 of the Chassis Service Manual but they are drawings, not pictures, and the detail isn't crisp enough to make out what most of the ends look like, nor are the drawings in color.


Servexcell,


You can find the Chassis Service Manual at www.wildaboutcars.com. The electrical is in Section 12. I sent you the scan of the wiring diagram.

 

Conceded.

Still helpful, though.

If your wires are no longer in connectors... necessary.
Generally what you find is an unmolested harness or one with 3 or 4 hacks for radio or lighting mods.

That's where your wiring diagram comes in handy.

Most connectors, by far, will be obvious where they go, by the shape, indexing tangs, Absent wire corresponding to absent pin, etc.

 

Thanks everyone for your response. I removed the dash yesterday and I have some wires that were burn't 2 whites and 1 orange. I do not know were they go . Most connectors are there but a few were not connected. I saw some diagrams on Wildabout cars are these them.

thanks

White is the ground path to turn on the dome lights.

Orange is the constant hot for dome lights and cigarette lighter.

Usually, the orange is burned because the cigarette lighter malfunctions and shorts.
As it gets hot, it melts the white wire next to it.

can someone please send me wiring diagram my email is crxr61313@gmail.com thanks

 

Hi crxr61313 I just sent you the diagram

Bruce

 

Thanks Bruce,


I'm not very good at replying but I sent it to him last Saturday too...

 

I removed the complete wiring harness yesterday and while disconnecting it , unbolted the fuse box panel from the firewall. while doing this i unclipped the fuse box from the junction box and unbolted the engine wiring harness. When i removed it from the car i found a brown wire with a terminal attached to it . hanging loose i am not sure were it goes to. I will send some pictures

thanks bruce

 

Engine compartment light.

- Eric

 

If your car had a tach the lead was dark brown.

 

Is it a short brown wire that sits on the engine side of the firewall, or a separate brown wire that's longer?

- Eric

 

Thanks Guys I will try and get a picture of the harness with the disconnected wire this weekend.

Bruce

 

A light brown (tan) wire with a single pin round connector is for the brake differential pressure switch. It plugs into the brake distribution block on the frame rail below the master cylinder.

A dark brown wire with a single terminal rectangular flat blade connector is for the optional under hood light.

Again, this is spelled out in the Chassis Service Manual wiring diagram.
