Pin outs on here.

Looks like it's pin 39 blue/red.

Other things to check are -

Check voltage on fuse 15 with key on, if ignition switch is playing up, you get less voltage on fuse 15 and this feeds ECU.

Also check relay '30' if it's hot when running replace it.
Also yours will have a '109' relay which is for ECU,check that too.
