I'm in the middle of converting my 77 to intermittent wipers. I swapped over to the 78-83 pump and wiring and tested it out with a 78-83 non intermittent switch and it all works. All I have left to do is cut and drill the dash opening for the new style switch.
I ordered a new 78-83 intermittent switch from LMC. I've been reading around here and it just dawned on my that there is seperate module that plugs into the switch. Somehow I get the feeling that I'll be getting a switch in the mail but no module.
I found AC Delco part #D6355A and I'm hoping these are still being made. Anyone know ?
I've taken lots of pics and documented it all as I've seen in past threads there was a lot of people who wanted intermittent wipers on their 73-77. I'll try my best to get together a definitive how-to on this topic. The 78-83 pump, wiring, and non intermittent switch is installed in my 77 and working. Just gotta get that intermittent switch and module.
EDIT: Just found the module for $95 on rockauto.com.
Might just have to stick with the non intermittent switch until I can afford that stinkin module. I'll still put the how-to together, since converting to the 78-83 wiring and pump is the meat of the conversion.
