The last post is probably right. Relay was originally located above drivers footwell in dash around the top of brake pedal. The only reason I mention this is I was not sure of year they moved it to the engine compartment. Was above the drivers footwell in 1977 for sure. I think a way to find it easily is to find and follow the lead from the glow plugs. It will go to a strip fuse holder. From the other side of the strip fuse it will go to the relay I believe. Just not personally familiar with your year.

My '80 wagon had the GP relay on drivers side inner fender behind headlight, as mentioned above.

It may have to do with the pencil style plugs vs the older style.

This would help support the "old style" vs "new style" glow plug relay location. (or I guess it could just be a "year" thing) And voice, no worries. I'm guessing out my backside as it is........

I am not going on ebay to buy a 1980 123 diesel to find out. Would not help anyways as relay would probably not work. So the one way you can find it for sure. When relay has finished its function it clicks off. If your hearing is normal you should be able to detect it's location by sound. If all else fails ask the wife.

If you have the pencil style plugs then its on the inner fender. If you have the loop style plugs then its under the dash.

Glad in a combined effort we can nail down these large issues. Squiggly bare wires between the glow plugs should put the relay inside the car. Just normal wires to the glow plugs should identify its location to under the hood. Either way at this point function is more important than location perhaps. That is unless you have found out already it is not functioning. You might just be in the final transition year as well. Also quite a few of the series plug cars were converted to the newer function plugs and the original relay was left functional up on that pedal assembley with the conversion. Think all possible variations have now been covered. Tell us you found the relay yesterday.
