Progress finally ... (pics)

Hey thanks. I now see a bit better. The plastic that carries the electric from the IVR box and to the senders is cut. You then just jumped the gap with your wires and from there you can make whatever connections you need. It doesn't matter if positive is now negitive because of the re-wireing is set up for the gauge.

I'm going to have to look at it a bit more. Iron it out in my head. The lights to the gauges are 12v right? Hooked up to the dimmer? The gauges are 12v. So you skipped over the IVR voltage being only 5v's ?
