Allison Vim Relay retainer

Problem : The relays inside the Allison V.I.M. of my Diesel pusher RV would vibrate out of there sockets causing a variety of symptoms like no reverse lights or no engine start. Solution : A small simple spacer to take up the space between the top of the relays and the inside surface of the lid. My print fit tight requiring two thumbs to lock it into the lid. Use at your own risk !
