Did the glowplug conversion with the new pencil style parallel plugs on Saturday. As expected it made a huge difference for starting the car. The friend who made up the wires for me and I got to talking as he's pretty savvy electrically. I was explaining my curiousity about using the 5 cylinder glowplug relay and timer and he suggested a novel idea. His thought on how to connect it was to just take the 5th wire and connect it to one of the other 4 plugs so that one plug would have 2 wires going to it. This way the comparison circuit would be fooled into seeing the same value on all 5 lines. I asked about the downside to having 2 wires to one plug (I was concerned about it wearing out faster) and he reminded me that the current flow is controlled by the resistor in the circuit, not by the amount of wire or gauge supplying it. Thoughts? ...Kevin 87 300TD 282k mi 79 240D 157k mi
