Hi All,
Been hanging around for a while sourcing info for my conversion and must say thanks for all the info people have posted here,it has really helped.

I have every thing in place and the motor is running,but I have a few items I can't seem to solve.
1 The ecu is in and the harness has the ends marked for the dash lights IE
Engine arming light
Oil light
Water temp
Tachometer
Etc etc
Non of the above have any power coming out of them either constant 12v or Ign 12v.

Also as far as running a catalytic converter I will be running one but not sure which one to get.
I spoke to a exhaust guy and he says I will need a euro style what ever that means.
Motor is out of a 1989 Liberty so it's a gen 1 I think, can the early motors run with any cat?
Any problems as far as the motor was an auto car now manual,
Also will be running aircon any problems there.
Looking forward to your help with much thanks

Cheers Ian

Hi Ian, none of those wires will have 12volts, they are all grounds.

The check engine light wire is a ground, as is the oil light which you just connect to the stock oil light wire.

The stock subi water temp sender is not compatible with aftermarket gauges, just unscrew that out and screw the one for your gauge in its place.

Tach wire goes to tach signal wire.
Should also be fan relay ground, starter wire, speed sensor, a/c switch etc.

Thanks Joel,
So as I understand, the wire coming out of the ecu marked engine warning light is the earth wire for that light on the dash.
So I can test that by taking a test light and place the ecu engine warning light wire to earth on the test light and the active to 12 v ignition switch and when the ignition is turned on the light should come on and flash any falt codes is this correct?
If no falts the light should go off.
What if the light stays on?

Thanks for your help.

Is it possible to make contact via emails so I can swap drawings etc.

Cheers Ian

You got it, the wire coming from the ECU goes to the negative side of a warning light and the positive side goes to an ignition source.

It should come on when you turn the ignition on then go out once the engine starts, if it stays on its detecting a fault.

plugging the diagnostic plugs together will flash whichever code it is if there is a fault present.
