For the last two days I've been searching the Net for a wiring diagram for an older turbo timer I bought of eBay. It's pretty old, with three buttons to select between 1,3 and 5 minutes, and an "off" button. The buttons are small, about the size of a pencil erasor, and the face has a silver style trim. So it's not the "newer" one with the larger buttons.

Does anyone have any info about what the 3 wires do?

Thanks!

 

it should be a power, ground, one to both ignition wires from the s/w and a switched power that goes dead when the s/w is turned to off or acc. should be 4 wires...

 

Actually, there are three wires. But I figured it out with an ohmmeter. For the record, here it is:

Black: ground (duh)
Red: +12V (duh)
Green: IGN
