change to intermittent wipers?

[DadTruck]

My 83 D-150 has two speed windshield wipers, I hve found a 87 D-150 in a salvage yard that I think has intermittent wipers. To upgrade my 83 is it as simple as getting the wiper switch assy and wiper motor out of that 87, or is there more to it?

In addition to that you will need the time delay relay and several additional wires that connect the switch, motor and relay.

is the time delay relay close to the wiper switch? other than tracing the wires, how would I identify it?

thanks
