Re: Pulling wire from engine bay to dash

For all that want to install engine exhaust temp gauge at dash:

There is a very good Pyrometer / EGT / Exhaust Gas Temperature / that uses regular copper wires from engine to dash, INSTEAD of K-thermocouple steel wires.

Keith, before moving forward on your wire pull, recommend reading our post from 7 years ago.

Digital Pyrometer & Boost Gauges - VEI Systems

Features & Functions:

Exhaust-gas temperature gauges are susceptible to many sources of error due to the nature of the sensor-probe signals, which are very low voltage (in the order of millivolts), and since the temperature of the reference junction (typically where the probe connects to the gauge) needs to be accurately determined. Our gauge and matching probe comes with a controller that amplifies the probe's signal output near the source, and places a temperature sensor at the reference junction of probe. The result is a much more accurate EGT monitor!Range: 1800 degrees Fahrenheit or 1000 degrees Celcius

User-settable bargraph type (bar or dot mode)

User-settable bargraph scale

User-settable peak indicator mode

12-segment bargraph AND 3-digit numeric display

Park-light dimmer

User-settable day and night intensities (9 levels each)

Sensor included:

BTW, years ago we ran couple dozen wires all at one time from engine for future use. Some twisted pair for shunts, some coax, jacketed and different sizes of single wires. Laid them all on ground parallel to each other Identified them at either end, made a paper wiring drawing, and pulled them from engine to front left corner where they could be fed up to dash. Did terminate a few wires at our curbside house battery bay. Started wire run at top center rear firewall where OEM hoses & cables are run. Worked cables forward by working up on ceiling of each bay.

I've got a inquiry to see if they still sell a single EGT seems like all the gauges I could find were dual.

VEI has single gauge EGT.

I get mine from Banks and they sell whatever you want.

You could use a 3 wire RTD instead of a thermocouple. Then you could use existing spare wires from the engine bay to the dash.

If you already have the gauge and thermocouple then getting the wire pulled SHOULD be much easier than replacing a fuel line. 😁

Hope you get lucky.
