I am planning on installing my little pod of gauges I made, which has Boost, Oil Temp, and a Voltage Gauge. I was wondering where I could route the tube for the boost gauge, as well as a few wires for the oil temp gauge, where is the best path to get them out into the engine compartment? I am installing the cluster where the ash tray was, this is on the 1982 300SD. Also, what would be the best place to splice in the line to the boost gauge? Right by the manifold? Or anywhere along that line? I have no clue where I can route these wires and tube, so I need some help here....
