I wanted to see what the illumination (backlight) of the display would look like if I connected it to the dimmer (rheostat) switch.
In this pic, I soldered a male electrical connector to the rheostat.
This is the results at night.
I can now dim the backlight of the display. But at full power, it is the same brightness as it was wired directly to the headlight switch. I think my original plan of going with LED instrument cluster bulbs would counteract the brightness. As show by forum member Chad300dtd in this
POST. Although I don't think it is currently that bad. I can live with it for now.
The second item I want to report is the instrument cluster sticks out a bit on the top portion. It fits perfectly on the bottom and sides. The display box is getting interference from the steering column support frame. I tried fiddling with is but this is the best I can get, but I might resort to modifying the plastic back of the display box to give me more room. The suggestion that forum member billybob made on post #10 should definitely correct this issue. But I like to keep the Celsius display and I can live with it sticking out a bit.
I hope this helps.
