    I have a 1999 Tacoma TRD 4x4 with A.D.D. front diff that has stopped working. It is a manual transmission and has a manual lever for going into hi4 and low4. I think it is either the transfer case switch or the A.D.D. relay. I can not locate the A.D.D. relay. Any help would be appreciated. Thanks for any and all help.

    Should be behind the glove box on the right side.
