Here's an accident report from a mid-air in which the cabling between
canopy-frame mounted equipment and the panel may have played a role.
Unfortunately, the pilot did not survive.

With the increase of use of gizmos in the cockpit I think it is worth
warning the fliying community of this potential deadly mistake,
especially with glare shield instalations of instruments such as TPAS.
I almost fell trap to it myself when considered wiring my glare shield
installed TPAS to the glider battery. Make sure you can jettison your
canopy and bail out easily.

Be careful out there,
