Lamco Gauges

[nt_a_foz]

So iv got some factory lamcos got like 6000wires into 6.

Its got 2 reds, 2 blacks and 2 yellows.

Guessing red is power and black is negative.

And yellow is dash lights.

That right??

[zarnah]

yeap, red 12v, black earth, yellow lights

[nt_a_foz]

Cheers man.

Just put in they look good ;D

[zarnah]

now I have a question about mine haha, do the Lamco oil temp gauge's work off some sort of factory sensor? or do i need to find a sender for it? (im guessing its oil temp, maybe its water, but it only goes up to 50 degrees celcius so I guess its to let you know once the car is at a decent operating temp?)

What ones do you have? I have seen a few different combos, mine are Boost (in bar) volts, and oil temp

[Guest boostin]

Nah, oil can easily hit 100. And you need the sender for the gauge, they won't work off the factory senders.

[zarnah]

wonder what its for then? it just says temp on it, actually just looked at it and it goes from -20 to +50 ????? is it just ambient air temp or something? or intake temp? fucks me haha

[Guest boostin]

Yeah sounds like ambient temp.

[zarnah]

awesome, sounds like it will be a bastard to find a sender for then, would be interesting though to see what the ambient temps under the bonnet are with my non turbo bonnet with no scoop, vs my oem rs bonnet....

[zarnah]

or install the sender right beside the air filter and trial different CAI setups etc...

[GC8E2DD]

Boostin, are you able to look up a price on the sump bung oil temp sender for these units?

[Guest boostin]

Mmmm, don't think so. Was it a factory fitment on any model? Not an option either, but factory.

[GC8E2DD]

Hrm, apparently there is an OEM part number for it - but I don't know what it is. Also don't know if they were fitted at the factory (off the option list) or something done at the dealer. Quite a few Type Rs have the exact same setup, including a matching boost gauge off the steering column. In fact I've only seen the Volts/ Oil Temp/ Oil Pressure Lamco combo on Type Rs. I've seen a black faced version with boost instead of oil temp(?), but that was in an RA and it was in or below the DIN slot rather than at the top in a shroud.

[Guest boostin]

I'll see what I can dig up tomorrow.

[nt_a_foz]

Does anyone know what the story is with the oil pressure setup.

So i replace the factory oil pressure sensor with the gauge one.

THe gauge loom has 2 plugs one that takes the factory sensor plug and one that plugs into the aftermarket gauges.

So looking at the gauge setup, its got a box thing that all the wiring goes into.

So im just wondeirng how the ecu knows what the oil pressure is upto.

Is that what the black box in the guage set up is for?? so the sensor tells the black box and hte other loom from the gauge goes to the factory sensor plug so this tells the ecu??

Is that right?

[Guest boostin]

The only way we can get it is with a full kit, at around $2500. Can't even get the gauges separately.

[Stoffa]

The box is there to ditch the factory oil pressure switch without the factory ecu throwing up a "no oil pressure" fault.

You should be able to ditch it as your running the G4, but it wont matter if you dont.

Its a stand alone unit, so it doesn't send any oil pressure signal to the ecu.

Here's how the wiring goes on mine....

Volt Meter

Yellow = Lights 12v+

Red = 12v+ (switched ignition)

Black = Earth

Oil Temp Guage

Yellow = Lights 12v+

Red = 12v+ (switched ignition)

Blue/White = Earthed AND connected to Blue/White on Black Box

White = Temp Sensor

Oil Temp Sensor

White = Temp Guage Signal

Black = Earth

Oil Pressure Guage

Yellow = Lights 12v+

Red = 12v+ (switched ignition)

White = White on the black box

Blue/White = Earth AND connected to Blue/White on black box

Oil Pressure Sensor

Blue = Blue on black box

Yellow = White on black box

Red = 12v+ (switched ignition)

Black = Black in the black box

The extra Black wire that runs with the oil pressure sensor loom connects to the wire that WAS connected to your old factory oil pressure switch. The other end of the black wire connects to the black wire in the black box. This is the bit that makes your ECU think the original pressure switch is still connected so it doesn't throw up a fault code.

Clear as mud???

[nt_a_foz]

mines already been wired so it has 2 black, 2 yellow and 2 red so got that part sorte.d

But doesnt the ecu shut the motor down at low oil pressure?

[Guest]

No the ecu doesn't do that but the rod or seized bearings do

[nt_a_foz]

haha true that.

But then what does the oil pressure light on the dash work on..This sensor i assume?

It works on the switch (not sensor, it's either on or off) under the alternator.

[nt_a_foz]

yes i realise thats how it works factory

BUT

to run the lamco gauges you remove this switch

and replace it with the lamco one...

therefore its not there anymore and the lamco loom has a plug to plug the factory switch plug into

[Guest boostcut]

have you got joshes sender out of the old block?

So just leave the factory wire unplugged. No biggie.

[Guest boostcut]

you just dont get a dirty great red light in your face when theres no oil psi.

[nt_a_foz]

it is a biggie if as he says iv got no oil pressure lol.

Noone friggin listning to the question so will ask someone tomorrow.
