Getting an Autometer Speedo to work


streeteg

Recommended Posts

Have a swapped 260z with an RB 25det/RB20 trans--- Has a custom dash--- so the stock speedo is not there. Have an autometer and am confused on what I need to make it work---

 

All there is --- is one connection....so my question is what wire do I need? Is it an RB part or a Z part? any help appreciated...

Hmmmmmmmmmmm, this has been talked about atleast 10 times. here hold on......

 

 

Nevermind i guess not,,,, cant think of any good key words to search.......Cant remember, does the rb20 tranny have the electronic or mechanical speed sensor?

 

if its electronic the autometer web sight has a install guide you can download. its pretty striaght forward. I had a rb25 tranny that i was going to hook the elctronic speedo also but never got around to it.

Hey I just noticed the RB20 Tranny...this is a mechanical setup. The stock Z speedo cable hooks right up to it....You may need a differtnt color gear but that shouldnt be a problem.....

 

Anyone have product codes for the RB speedo gears.

The rb speedos are the same as Z31 and Z32 trannies. rb20=z31 rb25/26=z32.

what does different color gear mean?

 

I do not have a stock Z speedo cable---any part that is interchangeable?

 

color of gear is based on your final drive ratio - based on your tire size and and rearend ratio you can pick the appropriate color to get the best estimate of your speed on the speedo.

Per Datsun Garage

YELLOW is the 16 tooth for the 3.36

BLACK is the 17 tooth for the 3.54

BLUE is the 18 tooth for the 3.70

WHITE is the 19 tooth for the 3.90

RED is the 20 tooth for the 4.11

PURPLE is the 21 tooth for the 4.38
