Hello,



These plugs run off of 1V and not 12V like the pencil plugs, so here is what I used to test them before putting them in my car:


AC-DC power supply 3V 60A (most expensive item @ $25 CDN)
8 guage booster cable as wire
240D wire resistor (looks like "V" and not a "W")
glow plug
gp insulator
8mm nut
cord from an old microwave
various electrical connectors

I originally tried a wire resistor from my 300D (the one that looks like a "W" but it took longer to heat up. When I switched to the 240D one ("V") is was almost instant. The photo below shows the basic set-up.
