I noticed a lot of people are looking for the potentiometer value for making the 6cyl FJ60-62 tach work on a V8. Here is a picture of the install. The pot value is 200ohm. You only use 2 out of 3 lugs. The outer as you maybe can't see, is not used. Attach an aftermarket tach and calibrate yours as needed.
