1990 cummins tach
I got a 1990 cummins and i was wanting to put a tach on it, but not sure how. Ive heard there is ones that will plug right in, but not sure where to get them. Any help?

Dont think your truck has the plug in not till 91.5 . You can use any air core type tack and a picup from ISSPRO all you gotta do is glue two tiny magnets on your dampner at 180° apart . do a search on e-bay i found a nice retro isspro 3" tach for $25.00. If your wondering what an air core tach is its a pickup style tack that will have DIP switches in it to select the number of cyl .

I just acquired a "Dodge" (dealer Installed) tach from a 1991 Non-intercooled truck, which also works with the '89 and '90 trucks, as well as the '91 Intercooled.
They were available as a dealer install (as the '92-'93 style was) and have a very unique wiring and sensor that reads off the crank balancer. The tach itself looks and wires up the same as the '92-'93 tach does, it just has this very elaborate wiring harness. I'll get pictures of the tach, sensor and the wiring up sometime in the next day or 2. Mark. |
