65 Coronet Variable Speed Wiper Switch VS Two Speed Switch

[DanDokken]

Hello,

I have a 65 Coronet 500 purchased as a project and stripped with parts in totes....
Car is at paint and I am prepping the dash with a new harness from M &H
My question is the wiper motor and current variable speed switch with push button pump
My new harness from M & H is for a model or two speed switch, can I use this switch with current motor and wire up pump?

Dunno on pre 68 but on post 68 wiper systems switch must be matched with motor. If not, won’t work propperly. Underdash harness and plugs are the same for both. The harness just changes running to motor on engine bay to the diff motor, but both leaves the firewall the same on same plug.

I don’t think earliers will be diff.
