ok, so i ordered a glowshift wideband gauge. its the red digital one. it came with directions for it to install. there are 4 wires that are for power. orange, red, white, and black. the directions say the black goes to engine ground, the white goes to a 12v switched power source, and the orange is for dimming. i understand all that and have no issues hooking it up. however, the instructions say nothing about the red wire at all. where does it go? kthx

 

to your signal wire on the o2 sensor.

 

no its not the signal wire, I had the same problem its your constant power wire just conect it to the battery

 

red - 12v constant
white - 12v switched(ex: only has power when ignition is on=sunroof, wipers)
black - ground
orange - dimmer control

this should all be on your installation instructions

 

you would think that but aparently glowshift is retarted, I have the same one and it leaves out the red wire in the instructions

 

thanks blazin. that explains it perfect. it wasn't on my instructions. i assumed thats what it was but i didn't want to mess anything up.

i agree. they need to fix that ****.
