After Market Gauges

I've been thinking about fitting some gauges for a while now but have always wondered where the gauges get their readings from, well more so, how you wire them up to take a reading.

 

Im perfectly ok taking the dash apart and running wires if I know how to, used the guide on this forum to fit plasma dials and bar the needles all the electrical side of things was nice and straight forward, all be it fiddly. Someone once told me that the ECU keeps all the readings and that you just need to wire the gauges to the relevant pin but I'm not sure.

 

No need for a water a temp as theres the stock one but what about a volt meter, oil temp and oil pressure? Infact what gauges are useful to have? I know theres no limit on how many you could have but which ones are useful ones to have?

the whole task of fitting and wiring them is relatively simple if your remotely mechanically and electrically minded (your experience with the digi dash conversion shows your atleast that).

 

firstly you'll often find gauges such as...

 

oil pressure

oil temp

water temp

 

will come with the relevant adapters or tee pieces required to splice into a required pipe.

 

However, when it comes to escorts (later models) most everything you need to measure to allow a gauge to work is already inplace wiring wise.

 

examples,

 

water temp gauges can be wired into the existing water temp sender on cvh's and zetec.

 

Tacho/rev gauges (non-mechanical types) can be wired to pin 8 (iirc) on the stock ecu (tho its common to find that your clocks are wired for revs even if there isnt a rev gauge as standard).

 

Air/Fuel gauges can be wired directly to the lambda sensors found on both cvh's and zetecs

 

Volt gauges can be wired into any non restricted 12v feed (such as the stereo memory live or if your brave the main feeds to the fusebox....the latter gives a more stable reading)

 

beyond those examples there is of course the more specialized types of gauges that are specific to types of engines

 

eg, boost psi gauges, turbo pressure, intercooler temp etc, which are only really applicable to Turbo engines.

 

as I said, aslong as your minimal wiring and fitting savvy you can usually muddle through with the help of the electrical schematics in the back of the Haynes.

 

I fitted and wired all my own gauges you see in my sig (revs & water temp combination gauge, volt gauge and a air/fuel gauge) with relative ease and speed.

Couldnt ask for a more informative post, thanks man.

 

I'd be looking to get oil pressure, oil temp and a volt gauges in a 3 pod on the pillar. Volts sounds simple enough, wire the sensor into the stereo or fuse box live like you said. With for example the oil temp and pressure on a mk6 x reg zetec would you need to port into the oil somewhere? O yeh and from your experience do the guages come with super long wires, from the pillar to the back of the stereo is a fair distance. Whats the best way to provide the guages with power, I would think running them off the illuminator live would be a good idea, works a treat for the plasma dials.

Loving This, Thanks for sharing :thumb:

As said the latter is the better option for the volts as that source point comes directly from the battery and is very stable, be sure to use a solid permenent connection suchs as a soldered joint as the last thing you want if your FB loosing power suddemly when a wire comes loose.

With for example the oil temp and pressure on a mk6 x reg zetec would you need to port into the oil somewhere? O

 

Indeed they will, many such gauges come with universal Tee's and adapters to accomplish this with the minimal of mechanical work.

yeh and from your experience do the guages come with super long wires, from the pillar to the back of the stereo is a fair distance. Whats the best way to provide the guages with power, I would think running them off the illuminator live would be a good idea, works a treat for the plasma dials.

 

Generally no they dont come with long wires and unless your very close to the signal source point then your likely gonna have to extend the majority Im affraid.

I personally connected me lives to the nearest heavy duty ignition switched wire so I could be certian the gauges were isolated when ignition is off.

Epic, thanks shaw, leaving once again with my arse intact!

 

I assume the sensor wire can be extended with a suitable replacement, would speaker wire work for a the sensor, not for the live obviously?

you need to decide what gauges you are having, not all will run off the sensors already there.

 

If you want can chuck up the wiring diagram and info on how to set up the Prosport oil temp and pressure gauges? As that's what i'm running and very easy once you know how :innocent:

 

 

my x plate there is already a gap to run the wires through to the engine bay

Legend, yes please, where have you mounted your gauges?

I Bought an escort twin gauge holder, not a universal fit, so fits nicely on the A pillar.

 

As my temp gauge stopped working after the engine was changed I had a water temp and Oil temp gauge added.

 

I went with Prosport, as the the reviews I found were decent. Purchased off ebay as was the cheapest place to but them and I found a decent seller:

 

oil:

water:

 

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...e=STRK:MEWNX:IT

 

They needed a power supply, and trigger from ignition, and head lights. These were all taken from the back of the stereo, and ran the cables behind the dash, easy to access by taking out the dash insert and and speedo. The input from the sensors was run through the bulkhead directly behind the speedo, as the digi dials work differently there was a space.

 

the gauges when off:

with Ignition on:

with head lights on:

The gauges need the sensor input.

 

For the water one I got a spare hose that fitted into the top of the radiator, then an adaptor, 36mm to make it tight:

fitted:

sensor is hidden by the air intake.

 

The oil temp I also bought an adaptor plate, also needed for the pressure sensor, you can fit 3 sensor in it, and comes with blanks for if you don't. The one I bought:

It fits between the engine and filter, looks like this fitted:

Escort_Ross did all the work for me. And very happy, gauages run spot on!
