Serial data wire?

I was getting the power from the fuel gauge feed, and it must not have been enough to power everything. Im going to wire it up direct and see how it works.

For the fuel gauge, we took the internals of the original 68 cluster, removed the needle, and epoxied it into the camaro cluster, then put the camaro needle on. I had to run 3 wires out of the side of the cluster for the fuel gauge. Ground, fuel gauge feed, and signal wire. But it works good and much easier than trying to make the stock fuel gauge work.

We haven't done the final wiring yet. That was just when we wired it up for a test, so the voltage issue could be your problem. I'm hoping I don't have trouble with the fuel gauge, I'm using the fuel tank and sender from a newer Camaro, so it should wire straight up. Hopefully!

Is there any way I could get a pic of what wires you spliced into? If it was just the colors that would work, since I have the pinouts with the colors. I would appreciate it

No problem, I should be able to get a pic tonight. Might be a little later though because of valentines day and what not.

Ok, so I wasn't thinking about the fact that the guy that did my harness didn't just use the factory wires. All of the 12 volt wires coming out are red, switched or not. The OBDII port wire is a solid green wire, that and the oil pressure line are the only two I have hooked up other than the all time 12 volt, keyed 12 volt, and grounds. I have only tried this when I had everything running directly off the battery, not through a fuse block at all. I can take a pic of it and get it too you later, but it seems like this isn't much help to you.

Found this document on my computer that we used when we were hooking this up, the red font are the only things we used. I think that B9 might be your issue.

Yes I think that could be the problem too. The pinout I have is a little different than this one. Mine says A13 is the instrument panel lamp control, and I had both B9 and A13 wired together to the dimmer switch, but noticed the seat belt light is always on. Maybe the pinout chart I have is for a different car. Did you connect B9 to 12v or to the dimmer switch?

Thanks for going back and helping me with this, I really appreciate it.

I haven't done the final wiring yet, but I had it hooked to 12v key on for the test. I guess it would need to go through the dimmer switch as well.
