Hi guys,
I have a 1967 Olds Delta 88 Convertable. It has the 425 in it. The battery positve wire goes from the battery and connects to this box mounted on the inside of the drivers side fender. Then off of the same post it goes down to the starter.It broke. I have taken the pieces to Napa and O reillys and they have no idea what it even is. Any help would be greatly appreciated!!!!!!

 

It's a horn relay.

Horn relay and junction block combined. It can get expensive because it is also used on 60s GM musclecars.

It's gonna be either NOS (new old stock) or a good used one, unless you're knowledgeable and creative with wiring up a replacement.

 

Agreed.

There are a million of these things out there in junkyards, which should last more or less forever (even more if you include the '68-and-later units with the key buzzer). They were used on essentially all GM cars of the period.
It's also easy to duplicate its function with a terminal stud (also readily available in junk yards from cars and trucks from the '60s to the present) and a $5 auto parts store fog light relay.

Although this is a Buick site I think it's the same part. About half way down the page.

Also page 42 of the Fusick catalog. Listed for a Cutlass but I'm sure it's the same. $10 cheaper too

 

To the OP, are you saying there is broken part in the heavy cable between battery and starter? Does the car start?

 

This part has the positive battery terminal that bolts directly on it. Then the main power to the starter bolts on the same post. Out of the other side it has to small posts coming out of it

 

Right. It's the horn relay.

See posts above.

There is a horn relay availabe on ebay right now. 1 day left. It will fit your car. I know that it is not the correct year but it is what you need. I purchased one just like this last year for my '67 Delta 88.

15 bux is a good price for that- for that matter if you can get it for under $40 it's good.

 

Photos are ever so much more helpful. I have a '67 Delta 88, too, just like Jaybird, but mine's even a convertible.

I presume what you're talking about is the brown rectangular thing in the center of this photo?




This piece from the Buick site TripDeuces mentions looks like a drop-in replacement. It's about $80, but if you need one, you need one.






If you want NOS, you might also try this site:

I had very good luck with him in getting another part for this car, the bracket that attaches to the firewall and holds part of the throttle linkage that I thought I'd never find new and that it would take me a year of Sundays to find used. He had one NOS for very reasonable price.


And, yes, I know the bolt above it is supposed to have a rubber covering over it. The car didn't have one when I bought it, but I have one that I haven't yet installed.

 

Check that one for $15 carefully. You'll notice it has a secondary smaller post. Make sure you get the correct one. As far as I know the only difference is either it will have the other post or not. The one without the post is farther down that page but costs $55. Go figure.

One other note. I have purchased these in the past where the punched spade terminals have the punched tab facing the wrong direction. The punched tab only allows the connector to fit on one way. The wire connector will have a little notch cut out to clear the punched tab. You'll know right away if it's wrong because the horn will sound if connected backwards. Should that be the case just flatten the punched tabs back into the spade terminals and connect the other way.

 

I LOVE THIS> Thanks so much. Yiou guys are all awesome. I appreciate all the help that has been given

 

Of course we are. We're Oldsmobile people.

 

If you fail in finding one threw those sources send me an email. I am sure I have one or two.

Thanks

The one with one small post fits the Olds/Pontiac musclecars. The two-post job is for full-size Buicks and Pontiacs who often had another accessory lead for power windows etc.

1966-68 big Pontiacs ditched the second small post and incorporated the extra power lead into the (+) battery cable terminal. It's about as easy to find one of these horn relays as it is to find a (+) cable with two power accessory leads moulded into the terminal. And being as both I and my Pontiac bud despise cheesy-looking parts store replacement terminals, finding that correct battery cable for his Bonneville Brougham became a quest of sorts.
