if you have fitted a manual j3 chip it will now need to read the 0v-0.1V,- 5Volts In gear. from the neutral switch on top of the gear box.
so if you dont have the neutral switch connected the ecu will still read that its in gear.. |

Yeah. I do have the N switch connected to the loom otherwise the car would start in gear wouldn't it? That is why I'm asking where the N switch from the gearbox actually runs to inside the loom. Does it go to pin 30 on the ECU or is it only running to somewhere else to break the starter motor circuit?

Aha, so with a J3 in, the two wires coming off the nuetral switch go to the wires that previously had our resistor in that told it nuetral?
Do we split them? Because they already go somewhere else. Remember that manual loom you had fiend had some extra wires in there...maybe these were the split wires that then went off to pin 30 etc...

Yeah - I keep meaning to label all the wires in that loom and work it out. But it has the right amount of connectors for a T5 at one end, and has the correct connection for a manual loom plug near firewall at the other - just an extra cable to two. Like you say, it could be splitting the N switch out before it goes into the ECU or something.
I agree with you tho too --- The resistor trick as performed by everyone installing T5 without manual ecu is performed to a different set of wires in the engine bay and am not quite following what is going on here. Obviously the pin 30 is connected to the resistor trick to fool the ECU into thinking it is in N the whole time so that it drives. But with that installed, you STILL CANNOT START THE CAR with the manual T5 in gear (as we found when one of the reverse / neutral cables was incorrectly labelled right!????) Therefore the N switch and the RESISTOR TRICK are doing different things to different parts of the thing... By my way of thinking. UNLESS the wires are split somewhere and one lot goes to the ECU pin 30 and the other lot goes somewhere else to prevent you from activating the starter motor whilst in gear. Can you find a pin out listing like that for my EF ECU by the way!? |

You are more or less on my thought train there fiend. The wires that we have going from our nuetral switch are not currently going to the ecu. They go to a relay in the engine bay-hence on other manual conversion tutorials they just go straight to the starter relay and short the pins, not worrying about the nuetral switch
And yes the resistor trick we do in the engine bay does lead to pin 30. So I'm thinking that loom you've got with the extra wires coming out of the the same terminals, will be what we whack into pin 30. Just splitting the signal... I'll try find a pin out for ya, for this though it's the same principal. So what do ya say mr J3 fiend? Wanna give it a go? At the plug in the engine bay just put a couple of extra bits of insulated copper in the nuetral switch wires, and then jam them in where the resistor for the auto tranny went!

Mate - I just unplugged and plugged back in the bit of the loom with the resistor on it. This would tell the auto ECU it is in N at the resistor (which apparently is not enough to tell the MANUAL ECU that it is in gear?)
It's all a bit of a mystery to me, but I will cut open the resistor loom and put a wire between into it next to the N thing and put it back in... Which one was the Neutral again ?!!! 1.2k??? Uh,,,?! Didn't stall today, but did go dangerously close once or twice. Hunting idle from 200rpm (yes - 200!) up to 800 and almost stalling but then it gives itself a rev and settles down again. God bless the ECU. |

Ummmmmm, don't know which resistor...
Now the tacho, does that not only go down to 500rpm? Because all thats left below 1000 is half of the rest of the 1000rpm increments. You know? So either the dashes below 1000 count for twice as much oooooor it only reads down to 500.

So theres an LTD(EA-D series, the second model) up at pick apart with the full interior in it. I can get the whole lot, seats trims etc for $50!
But I've already got EF mont seats and trims in the car, any opinions anyone? Those LTD seats are plush as f**k. But would it be taking a step backwards??

Do it! Its not a step back, it matches the car. Plus its a bargain.

Oh and btw, did you happen to see if it had the bumper insert where the tow bar comes out?

By the way I swapped my springs over on Friday when I did the exhaust. Sits much better.
Thanks for confirming it for me. PS Hurry up and get that interior. Then pics! |
