hi everyone i need some help or advise

[95on39's]

i just put another 4.0 in my 95 and my o/d light flashes and my speedo and tach gauges r not working but the rest of my gauges r and i think i have a few extra wire connections that have not been used

Sounds like a blown fuse in the abs or the speed sensor is unpluged(located on the rear differential)
