Digital analyzer tach?

[Thump]

Could anyone help me connect my digital tach meter to my truck? It's one of those deals with volts, ohms, dwell, and tach settings, and I just can't figure it out! (like most of the time I'm sure it's dead simple and I'm just under thinking)

RTFM.. No seriously. It would have instructions and at least sensors to make it work.

Therein lies the problem. The old toolbox it came contained no literature for it. It's not a big deal, I'll probably never use it but I thought I'd check it out.

Make and model?

Sent from the dust in front of you!

If I recall the stickers correctly is an actron model 856, or maybe 858, I don't remember and I'm not home to double check, but I'll verify later.
