No, a 126 cluster will not fit a 123 dash and vise-a-versa. The gauges are the same (mostly), depending on the year.

79Mercy has a point. If you want a boost gauge, buy one.

Diesel engines do not "create" vacuum (no manifold, either), there is a gear driven mechanical vac pump to operate the various components, such as, the power brakes, door locks and HVAC. A coupe has a vac lead for the front seat back locks as well.

If you take a lead off the VCV, you'll get a false reading. Which doesn't matter, as there is no such thing as an mpg gauge on a diesel. Use your right foot to determine that.

I have no knowledge of how to connect an outside temp gauge. Newer 126's have this too.

Yes, a W124 exterior temp gauge will fit into the W123 cluster. Deliveryvalve did an excellent write up. beginning of this thread he used a W126 gauge and later stumbled onto the w124 unit which fits better and is smaller.

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works

Let me correct myself, the tach/clock is the same unit, yet in a different housing, so you can't swap it from one cluster to the next. The rest of the gauges are not the same.
