Topic: 1967 seat belt warning light relay

[Hipo giddyup]

 So my seat belt warning light hasn't worked in sometime and I am finally getting around to replacing the relay. I recently picked up a bunch of the warning light relays in an NOS parts lot I purchased. My question is the location of the relay?? Is it on top of the pedal support like my 66' or perhaps somewhere else tucked up in the dash. Just wanted to know the exact location to save time and perhaps not have to pull the cluster if there is no need. I know there were A LOT of running changes in 67' maybe folks can chime in as to where theirs are located. Maybe even different between the plants? My coupe is a Metuchen build from late October, early Nov. of 1966. Thanks!

It should be mounted to either your Wiper Motor mounting pedestal bracket or a bracket attached to the same pedestal bracket, depending on your optional equipment.

Got it. I think I should be able to replace this without too much trouble. 
Thanks Richard.

 I just went to the garage and replaced the seatbelt warning light relay on my 67. To my surprise it was a cylindrical type relay with autolite stamping and C7AB part number. Haven’t seen these available so I’m assuming this was an early style or oddball 67 year feature? I did replace it with a C7AB relay but the rectangular shaped version. Either way the seatbelt light works fine now.
  Here are a few pics of the cylindrical 67 relay, which I believe to be original to this car, and the rectangular type which in this case is an NOS D2AB model for comparison.

 And to add to this post, this was quite a pain because of the tilt wheel pieces and the car having the floor console! Replacement was totally done blind.

I've seen both styles, and have some on hand. Unfortunately I don't know the origins.  Maybe I can look at date codes which might help. John

Typically if the same engineering number on two parts and one is a different looking part it could be explained by a different vendor. I have also seen the two types but could never determine if it was a early late vs different vendor. I am leaning towards different vendor.

That makes good sense Bob. Maybe even a Metuchen thing with one vendor to another, which is where this car was assembled.?

The engineering numbers differ only by the suffix when rectangular is also assembly-line C7AB- version. Rectangular is -B1 and cylindrical is -B2. I can say I have only found the cylindrical relay on earlier 67 and maybe 68 cars. Never found one on a 69-70 car, only rectangular. Have found rectangular on 66 cars with seat belt light but marked Tung-Sol without printed engineering number. Early versus Late wouldn't seem logical in that scenario. Maybe the cylindrical version is just from a second supplier for a certain time period to pick up some slack from the first supplier? 2nd supplier might have provided only certain assembly plants?

For 67 I have seen both types used at SJ. Enough at various times during production that I couldn’ t Contribute it to a early late thing for sure. It could be the same thing at other plants but I havnt studied them.
