this is for an 85 but quite sure it applies to the 86/87 - maybe someone can verify -
this should get you started

Thank you this should do the trick appreciate it
assuming original wiring from the turn signal switch down the steering column, the white wire at the connector (under bottom of steering column) is notorious for breaking because of the bend in the wire at that connection. Check there first.
