V8 ABS light on--Speedometer not working--any idea?

[busanostra]

Just finished doing my clutch and dual exhaust to my V8.
While the car is on the lift, I run the car.
The ABS light turned on and the speedo didn't work.

Someone told me the ABS light will turn off once I run on both tires (front & Back).
Is Speedo sensor also in the front?....(also not working).

Used to work before I did the clutch & exhaust system. Didn't touch
anything to ABS & Speedo sensor.

I tested the car today and the Speedo still not working and the ABS
light still on. I ran the car 5 miles.
Do I need to reset the ecu?
Where is the Ecu connection (OBDII) plug located?

Thanks a lot

The ABS and the speedo is now shared on the late V8's. It's the sensor on the right hand rear wheel. This sensor may have just packed in. try resetting your ECU first but the ABS is on a different ECU.
Also check ypur fuses although this is unlikely.

Thanks Dave,
You mentioned, the ABS is in a separate ECU. To reset the ABS ecu the same
as doing the OBDII in the Engine ECU?
Is the ABS ecu located behind the battery area?

Another question, I don't have a OBDII reader, is there any specific OBDII I need to buy or I can pick any OBDII reader in local auto parts?
My V8 is 1999

Thanks a lot.
