4d55t injection pump tach

[Dcollins311]

Hey I just put a 4d55t in a 1990 d50 2wd and have ordered a Dakota digital dsl-1e to run the stock tach and need to know the tooth count on the pickup in the injection pump. I can’t find anything on line.

I installed one in mine but didn’t need to know the tooth count. It worked as soon as I hooked it up.

Thank you cdalejef.

You ever get this figured out? I just got one of the dsl1-e's too. Seems more complicated than the earlier dsl-1's without the display, and i couldn't find one of those to buy...

Let me get back home to it this evening and I’ll let you know. Can’t remember how i did it my self.
