How do I wire this in? Is there a module/sensor for a pickup on the alt. or how does that work? Its an early 91 so theres no tach pickup already on the truck. Thanks.

From what I understand you have to take your alternator to a shop to get them to wire a tach output for it... As far as the specific tach, I cant help you there.

You got a part number or a link for that bad boy?

Just found it, it only works on electronic injection diesel engines.

I know people have installed this tach before. Can anyone tell me how>?

According to the ISSPRO website, any two-pulse per revolution sender will drive it. (Page 39 of their catalog).

Can't readily find one there though.
