I have had a look in tech docs and found 2 ECU pinout docs for EEC-IV and EEC-V. The IV version states it is for EBII onwards.

I have a wiring bunch from a 1990 EA II Anniversary and am trying to determine which LPG wires connect where. Can I safely assume that the EA II had EEC-IV and the ECU plug wiring was the same as the EBII, as in wire colours?

If not, does anyone know of a pinout/wiring diagram for an EA II ECU?

Cheers
RD

Of course, thats right! - it did have a seperate trans ECU! Bugger, don't want to outlay for another manual that would be only for finding out which wire goes where. I'll try and get a wiring diagram for the LPG system I have instead and that way I wouldn't be wasting money.

My EB1 has, well had, the separate TCM, and LPG.

The Engine ECU pinouts are the same for EA to EL, excluding EF of course.

The LPG setup should only interface with the injector signal lines, and fuel pump line, to disable them when LPG is on. The HEGO and Fuel tank lines are intercepted to allow for switching of devices depending on fuel being used.
