Ok it's done!! In and working fine. Hot, the oil reads 70psi, temp, 190f (192 stat) and volts at about 14V or maybe a little less, hard to tell from the driver seat.
Before anyone mentions it, I did mess up, just noticed when I took the pics. I installed the 'box' upside down!! Something to change if I ever take the dash apart again. I was getting really frustrated with this project and mistakes happen.
As for the tubes, I hid the copper oil feed in a rubber windshield washer hose for protection and looks and is barely noticeable. The temp feed is quite delicate, so I wrapped it with some plastic spiral wire wrap I had on hand. I then wrapped that with black loom wrap to the coil feed wires. The section from the coil to the pick-up sensor, I covered with that corrugated black plastic sleeve material. The result is nothing looks that out of place, which is what I wanted to achieve.
Job done!! I will post a few more pics when I get the car out later today with the engine hot and running.
Thanks to all for your input and help. It is very much appreciated and really what this great forum is for, helping each other.
Geoff.
