Mine looks like your pic....located under the dash behind the tach and speedo (accessed as you have indicated). Also on the '85 model relay, Bentley (if it's correct) shows the battery/ignition wire connected to #86, the fused wire connected to #30, #85 to ground, #85b to the door contact switches and #87 to another fuse and eventually to the power window switches. Anyway, I'm a "bush league amateur" when it comes to electronic issues and really have to depend on a step-by-step (with pics) method for troubleshooting. Will shut up now.

Marc,

Here is a copy of the factory manual for our '86 which I think is compatible with the 87-89.



Along with the relay location.
