Fixing the wiring of my tach - I'm dumber than a blonde!
CLOSED! After finishing the Harmonic Balancer, I got back on this. I thought about what was right and what was wrong, based on the schematic attached a few replies above. I also bought the circuit tester and some glass fuse taps. The picture in the previous post is BEFORE, the picture just above is AFTER.
Before:
That little black thing at the bottom is some kind of calibration for the tach. I noticed it was sitting at like 600 rpm (when off). Then I remembered I had fiddled with that thing not knowing what it was. So I fiddled with it again, and set the tach at 0 rpm.
Overall, I don't like this tach. I may update this later. But it is good for now.

Before:
- Switched Power (pole) was terminated straight to the battery (black wire, with a disconnect near the battery).
- Backlight (dark blue wire) was crimped in with the Switched Power, which was hardwired to the battery.
- Trigger was correct (light blue wire).
- Negative was grounded on paint under the dash (yellow wire).
- Switched Power, I pulled the yellow wire over to that pole, because it was grounded near the fuse box.
- I removed it from the painted ground and terminated it to the ACC fuse, using a glass fuse tap.
- Backlight, I snipped it off the black wire crimp, and extended it to under the dash, then terminated it to the LAMPS fuse, using a glass fuse tap.
- Trigger, I did not change.
- Negative, I pulled the black wire off the switched power post and moved it to the NEG post.
- I then disconnected the termination from the battery + pole, and attached it to the battery - post, as there was an attachment readily available.
