On a Corvette pin, there a 9 flash lamps in the backbox. The manual only shows 8. All of them, except one, light up when they should. I can't figure out this last one.

The flashers have the black sockets in the picture. The one in question is on the right edge, a little more than half way down. It looks like is has a blu/blk drive wire. The lamp on the bottom edge, 2nd from the right also has blu/blk, but they are separate wires and I do not see anywhere that they connect together.

All the wires connect to the driver board match up with the solenoid/flasher table in the manual. Wires are connected to J124 1-2-3-5, and J125 5-7-8-9.

On the front of the back glass, this mystery flasher would be right at the lower edge of the "Route 66" sign.

Any help would be appreciated!
Thanks!

I wouldn't rely on the manual.

Go into Flasher Test - step through them until you get the one you want. Hit the start button and then start hitting the + diagnostic button and this steps you through flasher, wire colors, fuse, connector info, transistor, etc.

Or step through them one at a time until you find the wire colors you are looking for.

Thanks LTG,

Went through all the flasher tests and all passed and accounted for.

Thanks zaza, you are correct. I just partially pulled apart the wire bundle, and found where the blu/blk drive wire "double backs" and goes to both flashers.

Then I was back to the flasher bulb, damn led wires, bent them a little and now it works! Even though I already did that a few times and even swapped it out twice.

Thanks for help!

All fixed.

No I can move on to adding in the #89 flasher under the right ramp, #22 in the flasher test. I guess they decided to leave it out.
