Jeep/Chevy Tach Question

[BigBlkYJ 355]

Im really wondering how hard it will be to keep the stock tach in the jeep. Someone told me that with the correct resistor inline with the tach signal i could make it work. Anyone know what the resistace from 4 cylinders to 8 would be. Ive got all the gauges nailed down so far except the tach and speedo, which i think i may be able to use an electronic sending unit from a 231 and somehow set it up to work with the cable drive from the NP205.

Thanx Guys

I believe you will need a 90 ohm resistor to make the jeep tach work with the chevy distributor. I will try and find that info out.

IIRC the cable drive and electronic/mechanical sender in the NP231 are interchangeable. When you pull them out compare them from the connectors down.

This has nothing to do with the speedo...

well i kinda mentioned it in the 1st post, but its not going to be a 231 going back in, and i doubt a 231 sender will bolt to a 205 t-case.
