Check out tech tips for signal-stats from cletis.
I have just acquired a Signal-Stat 105Y78 Flasher setup (NOS), but it has no wiring instructions. I looked in the Tech Tips and couldn't find the one you're referring to. I'm wiring a 1965 Chevrolet C-10.
My unit has a part number on the original box as #2234058, and the label says it's a Flasher - Emergency Switch for a GMC. It has the following wires coming out of it, in this order:
* Orange: pigtail to flasher unit, which pigtail's to an inline fuse
* Light Blue
* Dark Blue
Other than the Orange, which is obviously the power lead, I have no idea what these do. I'd really like to wire them into my harness using connectors like a junk Model 105Y79 I have has on it (got at a salvage yard - was connected to a truck, but never installed in mine), except the "79" has only 6 wires coming out of it.
Can anyone help me?
THANKS in advance!
