Interesting, let us know the results.

I have 2 GV's OD's 1 in my 49 GMC and 1 in my 70 GMC, I power them both directly from the battery (acts as a huge capacitor) with a power delay relay for triggering them. That solves 2 known glitches with these things, RFI and low voltage.
Both are working flawlessly.
