fitting a monster tacho (rb20)

[Guest boosted s13]

just wanting to find out some info on hooking up a monster tacho in a rb20 i got the power and ground - thats no prob. its the

wire that actually sends te reading i having a problem with. i know it can hook up to the computer.... but i aint that smart and got no idea where on the computer. i have also heard u can run it of the crank angle sensor wires but i got no idea which one. can anyone help with this?

yeah mate pin 7 on the computer is the tacho output wire.

Thats for a silver rocker cover Rb20. you should be able to splice into it and run it off that.

another thing pin 7 is not the 7th pin along, you will need a pin out diagram for its exact location, sorry i dont have one

u may need a booster as well as the ecu rpm wire is a 8volt and if u have a autometer tacho thay run at 12volt as far as i no this is what iv had to do and this site will help a lot www.rb20det.com thay have a ecu wireing diagram thats easy to read
