i just finished my 1jz swap in my 94 sc300 5 speed and my tach dosent work. so i purchased the MSD tach adapter and i have no clue how to wire it. i tried searing on here, but couldn't find any guides. i would apreciate it if any one new the colors i would need to splice into. Thanks

 

To make the tach work, you should be able to jump resistor r109 on the gauge cluster.

There should be no need for the msd.

 

i read somewhere that jumping that resistor doesn't always make it accurate.

 

Drift motion has the wiring diagram on their site.
