Hope you can help a neophyte...
I have a 77 targa with 915 transmission. I am off by 10% linear (speedo reads high). I dont really want to drill into the speedo to adjust the pot..likes like giving a knife to a mass murderer. I assume I have a sensor on the transmission that picks up the pulse (should be a square pulse then) Where do you install the yellow box....behind the dash? Which wire goes where if I do, I can power source and ground easy enough...I figured if I could take the inbound to the speedo and re-route to the yellow box, then back to the speedo, I could even mount the box in the smugglers compartment or behind the blower.
Click, Chris, 555......I am a pictures guy..any chance you can grab some photos of your set up and show me all the connections? so I get this right, Lyle..i got your PM..thanks
