Thanks Bio! Thanks a good chunk of info, it will be a big help when I'm installing my gauges.
1) I think i figured out my answer, i believe i need to purchase the sender for the electrical oil pressure gauge (1-100 psi). Then i need to attach the Oil Press sender wire (left on diagram) to the sender. I believe this is the sender i need.
B) Answered
2) Answered
3) Answered. Going to buy the pigtail from ZZP (its cheaper)
3B) I now know the difference between a wideband and naroband o2. I also now know i cannot use my narrowband guage with a wideband o2. Is a narrowband o2 gauge ok or should i really go for the wideband?
4) Answered. I also found a really good write up on connecting it to the interior lights and the dimmer switch.
5) Answered.
If anyone can help with the remaining questions it would be appreciated. Thanks
