| Need advice on installing EGT Trying the install myself, here are my questions:
1. Connected the 12v power and ground but do not get gauge (Autometer COMP II) to light up, I know there is a thrid wire for the dimmer, but does this thrid electrical connection also provide power for the gauge light?
2. Where in the fire wall are you routing the wire for the EGT? Please be specific, pictures would help.
3. When tapping the exhaust manifold I understadn it is on the passenger side, correct? Where do you route the wire from the firewall to the manifold?
4. When tapping manifold what is the typical hole size? DO I need to tap the hole out or will the connector provided thread in ok once the hole is the right size?
