Attention: TDR Forum Junkies 
I just bought a shift light and a warning light, both in the micro-size, from Summit (Autometer, 5330 and 3239).
The warning light will be connected to my SPA EGT guage's external warning line, to be a brighter warning than the little blinking light in the guage now. My question is this: I have three of these bloody guages, and I can't find ANY of the manuals that came with them identifying the one or two wires in the loom that are for the external warning lights. Could somebody tell me which one is it, please?
The shift light will somehow be connected to the tach signal. This little one doesn't include an RPM trigger, so I'm wondering if there's something already in the truck to perform this function or if I should buy one. In either case, where would I connect it?
Thanks!
