What is the most obvious way to identify a rallye harness? I have two harnesses, and neither will connect to a wiper switch #2770380 which is supposed to be a variable speed wiper switch. The harnesses do not have plug-in 4 bulb harnesses for a rallye light bar, so I can't tell that way.
The correlation between the wiper connector and rallye harness is confusing me. Are there two different rallye harnesses, one for two-speed wipers and a seperate harness for variablespeed wipers?
