I’m pretty sure these are wiper delay modules. If so, anyone in readerland know of a way to test them? I reasonably sure they are good, or I wouldn’t have kept them.

Top one is '78-'83, the others are '84-up. I've always tested them just by trying them in a truck.

I don’t know anyone with a 78-83 truck with delay. I’m guessing those aren’t very common.

I used to have friends that when they'd get a used whatever from me,would ask. How do you know it's good? I wouldn't have saved it if it wasn't.

I happen to need one for my '79. I'd be willing to gamble on it. And send more money if it works?

I have an 83 C10 I bought new and my wiper delay is part of the wiper switch mounted on the dash next to the headlight switch

If you're selling any of the ones for an 87R10 I'd buy it. On mine the pulse board, like what you've got, doesn't work any more. They just have slow or a lil faster.

This worked on my 85’ K10. I’m not sure if the 87 is the same , but probably. $$$

Your switch has the delay control, yes. But there is a delay module under the dash.
