Greddy Full Auto Turbo Timer, I was wondering if anyone knows best place to install this unit (wiring-wise) not the unit itself...I was gonna doit today, but IDK where to splice the wires or if I need to...If it helps I have Defi BF Series gauges and people say you can connect to gauges, but I thought it must only connect to ECU ignition wires...ANYONE???

 

This has been discussed several times in this forum. I'm gonna do a DIY thread soon, just haven't found the time. Look under the steering wheel at your ignition harness, right next to those fuses. You should see several very thick wires. White is 12V constant, Black/Red is Accessory, and BOTH Black/Yellows need to be connected to Ignition. I would suggest a soldering gun since anything smaller won't penetrate well.
