Now every thing I’ve read and all the wire diagrams make it clear that there are only seven wires on the Signal-Stat 900. Mine has the seven shown on the wire diagram, plus four more- white--white/red--white/green--and red/green. Supply power to one white wire and they are all hot. Supply power to the red/green wire and it powers both front signals. My question is; is there a practical purpose for these four other wires in our old trucks (‘53)? Could the red/green wire be used to convert the front turn/park lights to running lights? Basically just curious. Thanks.

Check this thread and compare to your switch and wires. Jeremy | | | | | Joined: Nov 2009 Posts: 639 'Bolter | | 'Bolter Joined: Nov 2009 Posts: 639 | Thanks Jeremy. If he's right, that would make sense. | | |
