Raptor Shift Light Help
Have power, ground and found the tach wire under drivers side dash but can't get the shift light to light up at set RPM. Here's what I've done so far, any suggestions appreciated.
Power an ground picked up from the loose pigtail on passenger side. Shift light goes through tests ok when you turn key on. Picks up on changes made to switch settings etc.
Green wire is going to white tach wire. I found this wire by using a test light hooked to ground. With car running when I probe this wire the tach drops to zero. Probing other wires does not affect tach so I assume I'm on the right wire.
I set the shift light to 2200 RPM and get start up test but not light at 2200 or above. I've tried 1 on, 2 off and 3 on and also the reverse for dip switch settings.
Any guess to why I can't get this thing to work. I've tried connecting the probe to the green wire and then probing the white wire to make sure I've got a good connection, that didn't help either.
Thanks
