Don, just curious. The picture I saw on New Vintage's website showed a CEL in the right side gauge. Why not use the one already built in? Are you 100% sure that the CEL requires the POS signal? Just seems weird that the industry standard is a Neg signal from the PCM and New Vintage is totally different. Just seems like alot of trouble to go through for the light to work.

Yep, that's the one. It calls for 12V positive.

For whatever reason the gauge wants a positive drive for all the indicators. Both LED pins are not brought out, only the positive side as far as I know. Why they didn't do their homework is a bit of a mystery. There may even be a controller between the input signals and the LED's.

Because you don't have access to both LED pins.
