[project 911]

I have two part # 0 336 611 006, both seem to be dead at this point. I have tested many of the resistors and all seem ok except one, but it doesn't have any kind of color code for me to identify what the part is. I'm not much at reading schematics, but is there some way to identify the part and maybe get something at Radio Shack?
I have one schematic that someone posted of an MFI transducer, but it has a different part number.

I'm putting in a Autometer tach shortly, so I hope that will solve that problem, but it sounds like if I still plan to use the transducer, I'll need to send a tach signal to it. I figure that's how I burned these out though. Still confused. I guess I'm hoping someone will just say definitively that I can just take all that stuff out...
