Dash To The Finish

The last step in completing the tachometer project was hooking the signal wire into my dash tach. I needed to remove the dash to accomplish this. I also needed to make a few other repairs and modifications to my dash. This actually turned out to be a pretty big project.
First, I removed the old fuel and oil pressure gauges. In addition, I relabeled the water temperature guage to read "CNTRLR". I ran a sensor wire to the controller and was hoping to use the old water temperature sender to pick up the controller temperature. (So far, it is reading way too high so I will need to play with the sensor a bit more.)

I then added indicator LEDs in the dash for the main contactor status, the controller cooling fans, and the throttle control circuit that I will be adding to allow slower throttle response. I also added switches under the dash for the controller fans and throttle control circuit.

In addition to adding indicators to the dash, I picked up a few circuits at the dash that will be needed for the various controls and brought them out to the control board under the hood.
Before I knew it, I had run quite a few new wires. I finally hooked everything back up to the dash and reinstalled it. I then tested everything including the tach. Finally, I tucked all of the loose wires under the hood and test drove the car to make sure everything still works as it should. Now I can work on completing the necessary control circuits.

Looking great, Bruce! Are you driving it everywhere yet? Or are you still being conservative? You should be very proud of your handiwork.

Thanks Daniel,
I'm still being conservative with it. I received my new Link 10 meter which I will install soon. With that and the tach, I will feel more confident in pushing the limits some. I still have visions of the controller exploding - guess it's going to take a few miles to get past that experience :)
