Im using a heavy duty double sided tape. I cleaned the area real good with a degreased before I placed it. Hopefully it holds. I live off a pretty bumpy road and it seems to be holding. I have the wires running straight down and tucked trough right below the steering wheel. You can see where they run down on the middle pic. I can take some more pics tomorrow but it was easy. Two power wires using fuse taps. One plugged into constant power (dome light) and one in accessory ( cigarette lighter) and a ground. I used a tee connector to tap into the line going to the throttle body and that was it. That gauge makes it easy.How do you have that mounted to your dash?
Are you using double sided sticky tape or mounted with screws?
Looks good. ?
Any pictures of where you ran and how you ran your wires?
