I connected the speedometer to my truck last weekend. I spent some time running around looking for wire connectors. I found a used splice connector and tried to use that. It didn’t work. The next day I stopped by a local electrical shop only to discover they had recently moved. When I got home I tried a spring clip on the signal wire, and that worked. I went for a test drive and it went well, the speedometer was reading low, so I calibrated it the next day. Yesterday I made this video. I’m happy with how well it works, and found a couple issues to address. The needle jumps when just starting out from zero, and the motor noise could be heard through the radio. I’m sure I can fix that.
