Drax's JUN Prelude: Papa Smurf edition

[Drax]

@njord @wurlycorner ignore what i supposedly corrected earlier, my notes were wrong so ive put right in the initial post what colour the wires are.....jesus im a dickhead

so what goes to the sensor, 1x green and ...? as the sensors look like they need 2x wires going to them.

[wurlycorner]

Now I'm even more confused...
I thought we were talking about the sensor on the IM? Which can't be anything to do with oil?



Can you link back to the original post so we know which ones you're asking about for sure please?
(Unless it's just me being thick here and everyone else still knows what's going on...

General though:
Oil pressure switches are normally just a single wire connection, positive feed from the pressure warning light, switch closes/opens to ground through the switch body and engine block. If it's a 2 wire sensor, it means instead of earthing to ground via the body, it has a return earth wire and goes to earth by that instead. It doesn't matter which wire is connected to which side.

Oil pressure sensors are the same, but instead of an on/off switch, they vary the resistance.

Sorry wurly, i havnt structured my questioning very well.

IAT Sensor
i just need to know which of the two wires are which, as both the ATR and Lude IAT use just two.

Oil Temp & Pressure gauge wiring
ive got my sensor in place for both of them, but i need to wire in the Gauges.
Research hasnt brought much up yet on how to wire them in, so;

they both have 6x wires - 3x thin red, black & GREEN wires, and 3x thicker red, black and ORANGE wires.

i can get pics up if required of both gauges and both sensor ends.

[njord]

I think pics are needed as the ones ive got have 5 wires, one postive n ground for the back light, and then a positive, ground n sensor wire for the gauge

will do!

[wurlycorner]

IAT will just be a thermister (varies resistance dependant on temp) so it doesn't matter which way round you put the two wires on.

you da man! thank you Wurly

Oil Pressure Gauge


Oil Temp Gauge


Wiring Diagram (just found!)


so, from the diagram im not sure where "C" and "Orange" go for Oil Pressure?
and the same again for the Oil Temp, but is "A" this time an Earth going somewhere else?

[wurlycorner]

what the hell is that meant to be! (the wiring diagram I mean)

But...

For Oil presssure I would say that Orange needs to connect to the existing oil pressure switch wire - that's the one that will put the oil pressure warning light on on the dashboard.
C looks like it wants to be a switched ignition live.

And for the oil temp gauge, yes it looks like A needs to be connected to earth.

cheers Wurly, much appreciated ill give this wiring a go asap.

quick update in the meantime, some of the fueling ive manage to sort out.
AN fittings on the fuel rail




AEM FPR with a home made bracket to fit to the rear left of the firewall


AN fittings on the replacement fuel filter (double danny's old one)


needed to cut the fuel line in to fit this, so bought the screwfix cheap pipe cutter as advised...snip!


and AN fitting put on


home made backet to hold the fuel filter in place


and both fitted...like a glove!




the oil cooler is now fitted too, will get pics of that asap.
