If Any One Has Any Input I Replaced A Headlight Switch In My 87 And The Harness Cause I Had No Parking Lights, The Hi /lo And The Signals Worked Befor I Did The Replacement When I Was Finished The Signals Worked For A Few Seconds And Stopped What Could Be Wrong ? Any Hidden Fused Wires Etc. The Manual Doesnt Say Much Other Than The Norm Of Your 15-20 Amp Fuses Etc, I Have Parking Lights And Low Beams now. Thanks Guys .........................................

 

yea there fuses under the dash, drivers side. and under the hood.

 

where did you get the replacement harness?.. it sounds like you have the wrong year.

If you have a S4 you need a S4 light harness, if you have a S5, you must have S5 light harness.
