Hi! I've just bought a power seat frame (bucket seat) and now I'm looking for a wiring diagram so I can connect it. Hope someone can help me!

 

Another Swede! Welcome!
There are quite a few Swedish folks here; several joining in the last few days.

Are you needing to know about the electrical wiring within the seat or how the seat connects to the main electrical harness of the car?

Sweet looking 'vert!
It looks vaguely familiar.....................
What is the top color code??

 

Yes another Swede! Thanks! I just need to know how it's connected to the main electrical harness! The rest is allredy fixed!

How come it looks familiar?
Have no idea what color code is only that's white!

 

The seat would be connected to the circuit that runs the power top.

The 72 has a circuit breaker in the top left of the fuse block and a harness that plugs in next to it, which has a terminal for an extra accessory. That is where your seat can plug in. In my picture, it is the red plug. The orange is for the top, the big red wire is for my power windows.
The 72 fuse block looks like this - is it similar to your '69?


Your car kinda looks like mine! It appears that your top is a brownish color, like beige or something.
Mine is a non-stock buckskin color, but the original top color was beige... Good combo.

 

Thanks for the picture! It looks the same in my 69'. I was out looking in my car and I have three cabels exit from there probably the power top, temp gauge and something more that I don't know about. So do you still think I can plug it in? It's only a 20 amp fuse.

 

Can you post a picture of your fuse block (like how I did?) It would help a lot. I Do not want to tell you wrong.

Doug - sorry to hijack your thread...

 

As you see I've got one grey, one dark red, and one red. One should be the power top as in your car, and the dark red is the temp gauge and the red is the one I don't know.

Yes! Sorry about the hijacking!

 

The grey should be the top.
The temp gauge should be wired in to a switched power lead, to reduce idle current on the battery, as this accy power lead is hot all the time.
You could then connect the seat to where the temp gauge was connected. If you do not know what the other red wire is for, disconnect it and see what doesn't work. The connections are not factory.
My car had a mystery wire connected that same place when i got it and it was for a dead electric fuel pump that was over the rear axle.
It was just recently removed.

While you are under there, check all connections to those non factory wires to make sure they are properly routed, away from sharp objects, and connections are well insulated to prevent fires. You might find out where that one goes, too!

 

On a '69 Cutlass there should be an orange wire with black stripe with a black plug with two or three receptacles on it, hanging above the fuse panel near the signal flasher...this is an orange wire with black stripe comming from the power relay which is located behind the left kick panel that activates when you turn on the key, supplying power to the windows and power seat...the wire from this black plug going to the seat motor is orange with black stripe also (12 gauge)...try that... the accessory outlet on the fuse panel is for light duty stuff, not seats nor windows...

 

x2 My '68 GTO is like that along with the Vista Cruiser.
The seat, window and top circuits are protected by a circuit breaker that feeds the relay, there shoudn't be a fuse JimpeBoy. I think the seat motor itself has an overload breaker too? The relay power feed breaker can be in the fuse panel or attached to the firewall like the Vista Cruiser. I did my power windows and locks and there was also a wire for rear cigarette lighters along with the power seat feed, full size luxo barge harness. The locks feed straight from the breaker so they work with the key off.

 

I was out looking for the orange and black wire, but i couldn't find it! But I can operate my top without turning the key. I have checked the accessory outlet and to get power there I have to turn the key.

 

Okay so I guess the 69 is different then the 72...
Follow the gray wire from the red plug and see if you can see where it goes. Can you measure voltage at it? Is it there key on or off?
That circuit looks to be all kludged up by a previous owner.
In fact, do I see FOIL partially wrapped around the accy fuse?
I would suggest you find out what all is getting fed off that red plug on the accy fuse.

Do you have a relay behind the left kick panel?

Looks like you need a wiring diagram for a 69 model so you can get it put back to it's proper state for safety.
I am moving all these posts to a new thread, since it is more involved than we thought and it will get better exposure.

Let us know what you find!

 

It's a PAIN but to take off the left kick panel, you have to unbolt the park brake mechanism and then remove the grille from the panel (pry off) and then remove screws (4) and then move the bottom of kick panel inboard and downwards being careful not to damage the vertical extension of the panel going up to the pillar--then up in that cavity near the upper door hinge is the power relay (very exciting to remove if you have to)...

 

OUCH! I am too used to the later ones that have just one screw and it pops out afterwards...

 

I don't think there is a relay in the 69 for the tops, my 70 doesn't either but I will now look for the 72 relay harness you all mention and get that, jimpeboy can do that too just as added protection

 

My '72 does not use a relay for the top - it uses a breaker in the fuse block and can be run with the key off.
I have heard of other GM's of this year using relays. How confusing...

 

The '68's and '69's don't use a power relay for the top, but for the windows, seat and antenna...so the question is- does he have pwr windows or antenna? which would mean he would have a power relay in place for those options already...

 

The answer is no, I don't have either power window or power antenna. So the question is, can I do like Lady72nRob71 said and plug it in on the extra accessory on the fuse block or do you think the fuse will break?

 

Since you can run the top up and down with the key off, unplug that big red connector from the fuse block and see if you can still run the top. If not, disconnect the two smaaller red wires from the big red connector and reinsert it, with only the gray wire getting power. If the top runs, then I am ASSUMING this is how the factory wired it.
A 20A fuse is very large, if it was only meant to drive the accy relay. The relay may have only been used for when power windows were installed. The top may still run right off the fuse.
I am hoping someone with vast 69 knowledge can set me straight.

IF I am right, then I think it would be fine to connect the power seat to this red connector also, keeping the fuse at 20A. BTW, please check to make sure it IS still 20A and remove the foil bits!
The seat may draw similar current as the top, but it is highly unlikely one would run the top and the seat at the same time. Doing so could blow the fuse.

Of couse best option would be to add a accy relay, but we would need to know the 69 wiring diagram to be able to know how to do so.

 

Ok, thanks for the answer. Im going to test unplugging the big connector and se what happens. What you see on the pictures is not a foil bit, it's glue from some duct tape that were holding my spare fuses togheter. For the time beeing it's a 15A fuse, hope it holds for the seat, otherwise I could test with a 20A.

 

Now it's in place and running (the frame.) Have to wait until tomorrow before i can test it with the seat in place because i have to modify the mounts. Hope the electric engine is in good conditon so it manage to operate with the seat and a person on it.

 

Just put a board on it, sit down and take it for a ride!


Let me know what you found out about the wiring...

 

Going to test that after dinner!

Well what have i found out about the wiring? Not much, except that the top can be operated with the large red plug disconnected.
