2JZ anti lag & launch switch

[chw37]

Hi im looking to install 2 switches, one for anti lag and one for launch control on my supra using the G4+ supra link

Id like to get them installed ready for my tuner to start work but im unsure exactly how to wire them?

Im using 3 pin switches

I believe i need to wire to a digital input for each?

What about the other pins on the switches?

Thanks

I assume by "3 pin" these must be SPDT.  There are a few ways you can do it but the easiest would be; The center or common pin goes to ground, then either one of the outside pins goes to a DI. The 3rd pin wont be connected to anything.  You will need one DI for each switch.

The switch is just a little rocker switch with a small led in the middle

It has a ground pin, 12v pin, accessory pin

So im assuming accessory pin to the DI on ecu, ground to ground and would i connect the 12v to a switched live for the led to work?

yes sir.  Wire it exactly as you described.

Hi, sorry for opening up an old thread but the i am in the same boat currently and just one question as to where the ground goes. Is it to be grounded anywhere on the chassis or the ecu ground wire on the link expansion loom?

 

thanks

Chassis ground.
