115 GP relay

For those (all both of you) who have been following my quest to locate the GP relay it has been found. If you pull off the driver's kick panel under the steering column and look up you won't and can't see the relay. It is mounted on the right side of the steering column. This side is hidden by the formed plastic shield under the column. Without removing this panel, which is a bit difficult because the bottom bolt has to be gotten at from under the car, the only to see the relay is by removing the instrument cluster. This is not a big job. Once the cluster is removed you look directly down onto the top of the steering column. The relay is bolted to the column. It takes a 10mm wrench to get it off. The wires are long enough that you can drop the relay down and unplug it.

With the wires accessable you can use the opportunity to install a push button to by pass the relay in case of relay failure. The button can be mounted directly through the dash just to the right of the headlight switch or into the kick panel.

Thanks everyone for their suggestions.

115 300d pressure differential gauge

Does anyone know what the delta P on both the inlet air system and fuel system should be before one needs to change the filters? I have access to delta P gauges and thought it might be good to install them inorder to keep an eye on the filters.
