Non-starter after front end upgrade

Stripped the front off my Curvey today, and installed the new front end, all went quite well, however i cant get it to fire up on the button.

What i can tell is.

Lights work, kill switch work, indy's work, we've started it via crossing the solenoid plus and minus and she fires on the first go.

There is a meta alarm fitted and i have checked it's not the immobilizer .

We are not blowing any fuses any where, in the fuse box or in the solenoid speedo cable,

Wire we cut during thr install, we of course clipped the speedo cable and resoldered on the new sensor, we also clipped a blue cable that seems to be comming from the flasher relay up in to the front loom where it meets with the cables comming from the starter switch.

We have then the starter switch apart and the connects are solid with no wear.

I dont have a haynes or multimeter to hand but i'll have to travel home to morrow to get one.

Anybody got any idea's where to start with the testing? or what else could be stopping the starter switch from sending a signal to the ignition

Ehh yea, can a mod like close n delete this, it turns out we had a very faulty clutch switch, and it seems to have failed today during the damn front end install, typical
