ABS light on among other questions

My ABS dash light is staying on but really dim, It keeps making me recheck the E-brake (Ebrake makes it bright), Im going to delve into it after work.
Been tring to find a nice set of wiring schematics since my two books and the FSM are shadey on early ABS wiring at best.
Might be rear diff sensor?

Secondly

Are the 90-94 lower IFS control arms on 4runners and 4x4 truck the same?

Yeah, could be rear diff sensor. It's not a very common problem so I'm not too much help.

Yes, the control arms are the same.

Thank you.

Figured out and fixed, It was the sensor in the brakefluid reservoir lid, It fell.

Damn, I was going to say that but I could have sworn it was the parking brake light that comes on for brake fluid level and not the abs light. Sorry about that.

Actually you may be right,, I assumed the Ebrake and ABS shared the same light, I cant remember what lights the cluster has in it.

I guess I could unplug the peddle pulse unit below the PS pump and see what one lights up.

Or unplug the abs sensor on the rear diff.
