I have the shower of sparks bendix system which replaces the impulse coupling on the magneto. It has a separate box that needed to be mounted somewhere. I fretted over putting it on the left side were all the wiring issue, but space is getting to be an issue. Getting that left mag off is tricky so no need to make it worse. I mounted it on the right side near the inverted oil system. -Put some corragated conduit on some of the sensor wire runs. -Mounted a heat shield on the #1 exhaust to protect the cabin heat scat hose.
SOS vibrator mounted - have to order the parts to wire it. (p leads)
