R model gauge wiring

The R model panel is coming together thanks to a US Air Force instrumentations guy up the street who worked on F-100s and F-4s Just for clarification, the red light is for ignition which shuts off once the engine starts, is that correct? That is the info I related to him thinking it the only logical application. If so, he said he was using a timing circuit drive that would shut the light off once the engine is on. He also mentioned and this is for anyone using the Branda panel with CS gauges, that the fuel pressure dash light is actually an L.E.D. that he soldered a resistor to in order to prevent too much current running through it. He is a thorough guy using solder instead of crimps. Anyone else have any experience with these gauges and anything I missed?

LED's are a better modern modification IMO but small incandescent bulbs were used originally. The red light is for the alternator idiot light like on a regular 65 Mustang. It works like you describe when you turn the ignition key however it turns off because the alternator takes over from the battery. It will come on if your alternator goes bad ,problem in the charging system or a belt breaks or comes off. The green one is for turn signals and the blue  one is for high beams or sometimes used for a electric fuel pump .

F4's? Are you having him install 50cal machine guns? Where are you going to store the ammo belts?

I would LOVE to have two 50 calibre machine guns, one in each headlight.

I'll get the panel installed and let it snowball from there...

You didn't really think these were for brake cooling..........

And openings in the rear valence, are for where the oil sprays out.

Is the term "turn single" a military term?

Was that a finger slip on the "key board"?

Quite possibly the latter.
