im not sure if its pin 1 and 2 on the old afm plug, but its the 5m's fuel cutoff switch inside the afm... leads to fun diagnosis time if u don't hook it up
That plug has BATT, M-REL, +B and earth.

Yeh, i just checked the wiring diagrams and then had a look at the plug on my 5M air flow meter. It is pins no. 1 & 2. I should always check things before i ask questions. But thanx anyways

It's not the safest way to do it though and some emgineers may have a problem with it, as the fuel pump will run whilst the ignition is on regardless of whether the engine is running or not. Not very safe in the event of an accident!

The safer way to do it would be to use the fuel pump relay that comes with it rather than relying on the factory circuit opening relay. I assume you've seen this?
http://andy.supras.org.nz/ This dude went into so much detail, even my original 1GGTE wiring was simple because he explained everything

Yeh, i've got the fuel pump relay (the thing on the right in picture no. 4 correct?) but not the fuel pump resistor. I cant wire the relay up without the resistor right?
I'll have to get onto chris about getting that resistor. Or does anyone here have a spare one they'd like to part with?
Yeh i've seen andy's website, its great! I certainly wouldn't have gotten this far without that website.
The alternative is you can use the FPR, but bypass the resistor, it's only there for slowing the fuel pump down at low load, I've got an external Walbro, and I can never hear it.

Alrighty, thanx for the sugesstion. I'll look into the wiring shouldn't be hard at all to hook up.
Seems i left the fuel pump relay and resistor at Chris's place when i took the engine. He sent it down to me so now i have both.
Bit of an update here, i've got pretty much everything to do the conversion with now and have set a date of the 12th of May to start. I'd take a picture and show all my 'goodies' but the batteries are flat. So that'll have to wait another time, sorry guys.
Another question. I need to locate the oil pressure sensor. There are 2 sensors down the left hand side of the block. One towards the front and one towards the rear. Which one is the oil pressure sensor?
Neither, both of them are knock sensors.
Oil pressure sensor is just infront of the oil filter.
As for the fuel pump relay, most people just use the stock Circuit Opening Relay for that.

Cruz is indeed correct, the oil pressure sensor will have either a male spade or a little round lug on it depending on your engine. Either way the standard MA61 oil pressure light plug will go straight on (if youre going to use the idiot light and not install a guage that is)

Cheers guys, that was very quick.
I'm going to try and wire up the fuel pump with the fuel pump relay and resistor as how it was in the MA70. Why, because it runs the pump at dual speed and keeps the system more inline with factory spec.
I needed to locate the oil pressure sensor as i will be running a mechanical oil gauge. But i also want to keep the 'idiot' oil light, so i am going to run a T junction so i can have both.
Cheers again
Theres another bung (unused with a bolt in it) at the back of the block on the drivers side, might be a better option than running a T piece. Just a thought....Originally Posted by Negative Boost

Now that is a thought. Thanks, i'll check it out next time i get a chance to. Would be a much better location than having it all the way down near the filter.
Personally I'd ditch the 2 speed pump.
There is no real need for it.
