IMO install on HP2 Q's

I'm in the process of installing an IMO 100R-300 on my HP2 and had a few q's.
Whats the best wire to tie into for the rev counter feature on the IMO?
And has anybody used the rear brake disk for the speedo magnet?

Any help is appreciated, and I promise to post pics of it afterwords

Thanks

what's an IMO?

It's basically a fancy speedo/tach/odometer LINK TO IMO

Don't put the speedo pick-up on the rear wheel unless you intend to stick to the pavement. Accuracy will be out the window with rear wheel spin in the dirt.

Clutch

But I cant keep the front wheel on the ground

I already put the pickup on the front wheel. The reason I was thinking of the rear wheel was for the wheel swaps and not having to put a new magnet on each one.
I have every thing mounted up and working great except for the tach. Still trying to figure that out. I cant seem to find the Tach plug any where?

Hello,

Have you sorted this? I am trying something similar with a Qobix trip computer on an R1200GS and I'm also looking for a 12 V ignition signal.

Thanks,

Carlos
