How about converting to an electric driven gauge? I've never used this guy before, but the stuff on his website looks pretty good and he claims to be able to retrofit old gauges to look the same but use modern electronic guts. This would let you use the ECM to drive the stock looking gauges, and would let you not have to run separate lines for the ECM and the gauges.

When I had the gauges rebuilt by North Hollywood Speedometer they told me they could not rebuild the gauges with electronic components because the gauge is a combo gauge of Water temp and oil temp in one vertical gauge. I think I found some adapters that are pretty low profile. I will try that before going too far in another direction. If I am not happy with the look I will reach out to Bob's Speedometer.

IDEA: Run the wires through 'Tech Flex'. You can choose what color you want to use.
Maybe a touch of red on the ends with adhesive heat shrink for added "flair".

I will check into that. I was planning on using the heat shield sleeves from DEI for the plug boots but this may be a little cleaner looking.
