i need help to wire a electric boost controller and some electric gauges. i am mounting gauges above the the radio on the dash and just wondering if i can use the factory harness that the radio is using and just connect the battery ignition and ground wires to it and just fuse all the wires except for the ground.

 

You sure can. But I would recommend running a relay off the ACC line to allow for future mods. My Nexus guages are hooked up that way along with my Tcover. not much amperage increase but any more and I will convert it to a separate circuit so just the relay and the head unit are drawing current from the factory acc line. Just food for thought.

 

thanks. i have tohook up the brain for the nexus gauges aboost controller and a wide band do u think that will still be ok

 

I'd run the boost controller and wideband off of a different constant source than the radio, noise may affect the controller and wideband. But the ACC line should be fine.
