To answer your question, yes! It is possible. That's how I have it set-up on mine. The problem i ran into though is the pin for the rear wiper connector. I ended up paying $40+ for it because it's Toyota exclusive, and you can't seem to get anywhere else but the dealership.

You might have better luck finding it online though. I was in a bit of a rush, and never really bothered to check.

The part number is: 82998-24290. It's a direct fit for pin 6 of the connector.

I have the pins on hand if anyone needs them and I only charge $3 each for them.

Just the absurd small ones or the 'normal' pins as well. i might as well do some proper wiring vs my inserts.

I'll send you a PM

invader166 would you mind posting how you wired this ? Was my description correct?

You bet! I'll post how I did the wiring in the next few days or so. I'm currently away since I do travel a lot because of my job.

Generally speaking, the relay only comes on for 1/2 a second or so, to get the wiper moving. It will return to it's original position as a result of the eccentric cam profile of the motor. You do hear it click on and off when it operates.

I guess you can also make/buy an enclosure for it, to not have all the circuitry exposed, but it's completely up to you. I never really bothered with that, and ended up mounting underneath the steering column, hidden from view, but still able to access it to adjust the timing with relative ease.

Alright! Finally had a chance to refresh my memory.

I only used 4 connections to wire up the delay unit:

12V+ ---> Black wire from front wipers connector.
12V- ---> Missing wire from rear wiper connector. (pin 6)
NO ---> White wire with black stripe on rear wiper connector. (or any other ground wire)
COM ---> Blue wire from rear wiper connector.

Should work as if it were originally fitted from the factory.

Thank you sir, I'll give it a go later this weekend
