Hey there,
Was fixing the windscreen washers today on my 92 Astro LT. In checking everything for leaks, and making sure the pump was driving I noticed and additional connector next to the pump connector, it was coming off the harness very close to the same point as the connection for the pump, but from what I could see there were no components nearby that would ever be able to use it. Any ideas as to what it might be? I thought that maybe headlight washers were and option back in the day and maybe this lead drove a booster pump?
Cheers for any info...I hate it when I see a dangling unused part of the harness!!
