Ac Relay Staying On With Ignition Off Completely (Help)

[GTR260]

Recently installed a platinum pro ecu into my 260rs went to start it the next day and found the battery was stone dead, found that the ac compressor clutch was staying engaged after the ignition was off! Checked the relay and there is power to the trigger, what could be causing it to do this? I dont have a service manual, has anyone else experienced this problem? If so how was it fixed

Update, from process of eliminination i've found that it's the haltech causing it,

With the haltech in:

If i turn the ignition on the ac relay goes off

Turn it off the ac relay goes on.

Take the haltech out problem goes away

If i put the standard ecu back in problem goes away!

Will call haltech on monday to see if they can explain why this might be happening
