PLEASE READ:
Pack lights are NOT included in this kit!
A smoke kit is NOT included in this kit!
A Ghostbusters proton pack is NOT included in this kit!

This listing is only for one vent relay board and connection cable.

This vent relay kit is designed to work with:
1) GBFans powercell and cyclotron kit that has the RGB cyclotron LED boards and a 3-pin "Vent" connector for use in a full sized pack
2) GhostLab42 Spirit Pack Lights kits that all have the 3-pin "Vent" connector for use in a Spirit Halloween Proton Pack

This relay will probably not work with any other Proton Pack Lights kits, as it is only designed to work with the above listed Pack Lights boards.

Here is a link to the instructions (eBay hates external links):
