also that link only has 1 pinout?

 

just for the 3 plugs on the ecu.

 

and up the top there is a quick guide on what you need to connect in the way of powers etc for the conversion.

All bigports are not the same, check the board to make sure.

Can anyone tell me what the wires are to this plug?

 

 

This is what i have at the moment:

Red Black (or red blue) / Reverse lights

Yellow Green / temp gauge

Yellow black / oil pressure

Yellow / injector power (conect this to 12v switched on ignition)

Black white / starter signal

black orange / ign (connect this to 12v switched on ignition OR connect as discribed in the first part of the guide)

black with brown dots / tacho (old tacho wire will be found near the old coil, same colour (or just a plain black wire)).

 

There is a black wire that I am unsure of

id connect all those thigns up first, then see what doesnt work. sounds like you have everything covered there. that black one might be something obscure like Aircon turn on or something.

 

also rememebr that if you are using standard ke70/ae71 dash cluster, you will need to put the temp sender from the 4k/4ac into the 4age, else it will be the wrong resistance, they might be the same, best to check though.
