Wheel speed sensor

so after doing some research it looks like the abs/speed sensor for the rear axle runs off a magnet on the wheel bearing, and not a tone ring. So this is my problem, I just bought a 9” for my truck but there’s no easy way for me to hook up my wheel speed sensor that I can see so when I go to install it I’m gunna be without a spedo. I’ve seen people plug it into their transfer case but my truck is a 2wd automatic, does anyone have any recommendations or ideas? I thought of maybe splicing it into the front abs wire, but when I unplugged the front and drove down the street my spedo still worked so I’m guessing that’s not an option. Any help appreciated

 

Bump anyone got any sort of idea for me?

 

I highly doubt your speedometer is fed from a sensor at the wheel. Each wheel will spin at different rates when you go around a corner. The speedometer sensor has the be on the main drive line somewhere, most likely in the transmission or transferase.

 

I unhooked the abs/wheel speed sensor and my spedo no longer worked and it was only when I unhooked the rear not the front

 

Wheel speed sensors feed info to the ABS module which tells the cluster module the average and it displays this, thats how ford works at least, toyota may be different but not drastically different.

Any ideas anyone? Or does anyone know anything about gps spedometers and could share some infor with me?
