Dash wiring (Vintage Gauges)

[Junbug]

A few quick questions and a brief preface so you understand my situation. I daisy chained all of my gauges together keeping the same wire colors connected (and checked that they all light up with 12V). I kept the vintage red (gauge power) line disconnected for the clock as that will connect to the HAAT wire (radio-memory) from the dash harness.
1. As long as all the gauges get connected to the dash harness power, light and ground wires I don't need to connect additional power, light, ground wires provided by the stock dash harness? There are additional wires in the dash harness for power, light and ground wires that I don't believe I need because all my gauges are daisy chained together with a single tail that connects to the dash harness power, light and ground wires.
2. I plan to connect the wires below:
a. Dash harness brown wire (gauge power) to the red vintage gauge wire daisy chain tail
b. Dash harness white wire (gauge lights) to the white vintage gauge wire daisy chain tail
c. Dash harness black wire (ground) to the black vintage gauge wire daisy chain tail

3. I understand the Vintage Speedometer doesn't need a HAAT wire.

Thanks for pointing out any mistakes/errors.

1. Correct. There are extra wires in the Ron Francis harness that you may not need. Either remove or cap the ends of the extra power and lighting wires to make sure nothing gets shorted.

2. Correct.

3. If it's the GPS version of the speedo, there used to be an additional "quick start" wire that you could connect to a HAAT source. Intended to save the last location so the GPS acquired more quickly. If you have one, I'd suggest hooking it up. Looking at current Speedhut instructions, maybe they've eliminated this? Now says, "GPS location is saved internally for up to a 4 hour period. After 4 hours it will take 30-40 seconds to acquire signal again."

Also, depending on your gauge version, there may be internal LED's for turn signals and high beam. I used them on my Coupe build rather than having separate indicators. Makes for a bit cleaner installation. But they aren't real bright.

Thanks for the quick confirmation Paul. Regarding #3 above, the latest Vintage speedo gauge, at least the one I have, doesn't have a HAAT/quick start wire. Just the standard 3 wire (red/black/white) gauge power connector, a second 3 wire connector for the R/L/Hi-Beam indicators and the third jack button connector. Oh, also the connector for the GPS antenna.
Thanks!

While you are thinking about gauge wiring, you might want to consider purchasing another push button from Speedhut if you are using their clock. It is useful to have a dedicated button for the speedometer functions and a separate one for adjusting the clock.

Thanks for the tip James... Fortunately my kit from speedhut came with 5 of the jack button cables...
