Hello All,

This has probably been answered before but i cant find it.
Am nearly finished a manual conversion on my 93 Eb.
Have put an El t5 in.
I need to know which wires go where from the box to the rectangular plug.
There is no mention i can find of the speedo sensor.
From the gearbox i have
orange/red
black/white
white/red
red/black
white
red
black/green which at the end has red/blue joined to it with a separate spade terminal

At the rectangular plug i have
white
black/green
red
white/purple
red/blue
red/black
and another black/green which goes to the same spade

Can someone tell me which wires to connect where?

Your help would be greatly appreciated

Rectangular plug on the EB loom:-

34 - red/blue - switched ground via inhibit switch
296 - white/violet reverse voltage feed
999 - white Speedo signal
140 - red/black - reverse switch
60 -black/green - ground (trans and speedo)
998 - red Speedo supply voltage

Some of the The EL wire colours will match the same functions as used in the EB wiring:-

999 - white Speedo signal
60 -black/green - ground (trans and speedo)
998 - red Speedo supply voltage
The black/green and red/blue are related to the inhibitor switch which is bypassed for manual.
red/black - reverse switch
white/red - reverse voltage feed

The others.....
black/white = 359 - Signal return ground for Neutral switch (pin 91 (pink/light green) on ECU)
orange/red = 614 - Neutral detect switch (pin 64 on ECU).

The neutral switch function will only be applicable for a manual ECU

Thanks Muzza,

Will go and try that now.
hopefully the thermo's will behave themselves.

All working great. iTS a new car !!
If i wanted to hook up the neutral detect how would i do this.
Its a manual Ecu with 60 pins

Cheers

Only applicable to 60 pin ECUs .... Pin 30.
Grounded when in neutral.

That's signal ground though - pin 46 from memory.

Yes, correct...my omission...
pin 30 is connected to pin 46 to indicate when in neutral.
Pin 30 is the NDS input
Pin 46 is signal ground

Would i have to run the wires to the ecu or is there somewhere else i could tap into them?
The old auto plug maybe ?

When I converted my car, I just used the square plug from the auto loom and plugged it straight into the car's loom. If you get the neutral and reverse switches and the speedo wires to the right pins on the auto loom you shouldn't have any problems.

Well that's the thing, the pinouts on the square plug vary with model - i.e. plug in an EF trans loom into the EB engine side, and wires don't match up, hence use Murray's info and match the colours too.

Grab a meter and check for pins 30 & 46 on that plug, then you can put your 6.8kohm resistor across them - idle then should be sorted.
The pinouts on the round plugs are the same throughout the models.
