im looking for a wiring diagram for the greddy blue. or if there is a write up out there on how to install it on a 3.0L 5th gen.

 

check greddy's web page for the wiring diagram, Use in conjunction with the FSM for your year car and find the proper wires. Tap what needs tapping, intercept what needs intercepting.

I have heard diodes were needed to prevent the blue frying the coils. Hopefully someone else can chime in with more information or which specific diodes to purchase
