Not unless you are more specific with what you want and what you mean.

I have no idea what you have or what you want to acheive from what you wrote above!?!

If your entire loom has live feed to all of it then you have serious problems!!!!

im wanting to have the ecu power up from the ignition rather than be live all the time, its killing my battery, over 3 days it`ll be flat , its been this way for 4 months and now ive had enough of unplugging the ecu every night

Ok. I think I can see what you have got and what you want/need.

On the Cossie 4x4 loom, there should be 2 relays. 1 for the ECU power and one for the fuel pump relay. The ECU power relay should have a black wire to it which is an ignition live feed. This switches on the relay to supply the entire engine management system with power.

This black wire feeds the ignition coil, ignition module and also the lambda sensor (if fitted) as well as triggering the EMS relay.

This wire is NOT big enough to run the EMS on it's own which is why it has to trigger a relay which then supplies the EMS with power. If you try and run the EMS on this wire, you will either set fire to your loom or melt your engine or both!!

L6 engine loom as follows: green>rev counter. brown>coolant temp gauge.black/red>fuel pump. black>ignition power. blue/red>+ battery. if you have wired black to + battery, i pressume your ignition (dash lights on) is still live with the key OUT the ignition?

I doubt it as it would only power up the EMS....

If it lights up the ignition lights then the black wire must be conncted to ignition AND a premenant power supply.

L8 4x4 loom is as follows on a 6 way plug behind the battery (on a Cossie)...

Red with blue trace - main battery power supply
Green - rev counter
Brown with white trace - coolant temp sender for the guage
Black with red trace - fuel pump power supply
Black - ignition feed

There is a wire for the oil pressure switch but I can't remember what colour it is off the top of my head.
