Window Rocket - who’s tried it?

Just to add, and reviewing what has been posted.

I just wired up my Aux Fan Relay into the non-populated CDS relay socket in the engine bay. After testing to make sure everything worked, I wrapped all the wiring and reinstalled the relay box but then it stopped working. One of the prongs in the relay socket was slightly pushed in, preventing the relay from making full contact.

Given that, @jun85 take a close look at the Power Relay socket to make sure all the female connectors are in place, not damaged and/or not recessed. You might use your phone's camera to take a close in focus picture of the socket to check for damage.

Assuming it is the rear window defogger in your model, plugging the WIndow Rocket into that relay, even if you had the rear defog switch on, would have done nothing.

Check your starting battery voltage. With Key in the On position, make sure you have power on each fuse, on both fuse blocks: Engine bay and dash. ATO/ATC fuses can be checked in position...

There are relays above this relay block in his cruiser- That's where he plugged it in. The picture he sent me was hard to tell what was going on, but it wasn't plugged into any of the relays on the relay block.

Where did you have it plugged in before? The picture you emailed me showed it plugged into somewhere else, one of the "extra relays" above the main relay block in your picture.

I had moved it after you said to move it just forward of the big square black plastic relay. It was originally just above it, to the left (as you look at it)

Can you show a picture of that relay socket where you plugged it in? The pictures you've shown here do not show there's even a relay there, but there is.

If you can show exactly where it was plugged in maybe someone will know what that relay powers.

Will do.
If it’s any help, it’s a UK spec (cold weather) 80 series, 1994 1hdt.

Is this where you plugged it into?

Above is from a 1991 EWD. I can't find a diesel 1994 EWD.

The relay pinouts are different. 😰

The COOLING FAN CONTROL ECU normally controls that relay and it may have an issue,

Check its 15A fuse, possibly ECU–IG, as well as the 10A Dome fuse

Yes, that’s where I had initially plugged it in. Should I look and see if I have screwed up the pinouts?
I checked the fuses, below the steering wheel, and the ones in the fuse box in engine bay and they all seem ok.

Yes, check the pinouts of that socket, and the blades on the relay that is designed to be there.

Also, how do you check fuses? Do you Ohm test them or just visually? I would ohm test them, as well as check if there is appropriate voltage.

Will so. I was just pulling the fuses and visually checking them, but I will ohm test them asap.
 
I'm going to add a picture in the instructions with red X's or Mr Yuck faces or something over all the places not to plug the window rocket in.

The ABS instructions don't address those extra relays above the relay panel so I will fix that.

Wishing I'd have foreseen the potential for this problem.

I'm doing some family stuff this morning, but I will be in the shop later today. I will sketch up what electrical calamity happened when the WR was plugged into that differently pinned socket and report back.

You should also go back to stock for testing purposes. Reverse everything, remove the Window Rocket, and replace the original relays. Check if the issue remains.
 
I pulled out the '92 EWD I have for FJ80L's and compared the pinout of that relay with the window rocket and I don't think anything at all would happen if you plugged it in. There's no shorts, the WR relay wouldn't close so no higher voltage would be sent anywhere. I don't think the fuse would even blow.

My suspicion is that relay is used for something else in a 94 diesel 80 series. Do the diesels have an engine bay cooling fan like the FJ80 did? If not, then that relay definitely does something else.
 
Found this diagram showing the series parallel system employed in the HDJ80's.

No locations shown for any of these in this schematic, but it's possible that relay is the starter relay or the 24V hold warning relay.

Two fusible links are listed. Might be worth locating and testing those.
 
Hey PIP
I just installed my window rocket today. I wanted to pick your brain. After the install I noticed no difference in performance. Wondering if there is somewhere else in the system I might have an electrical issue. Or maybe I just need new motors?! I have all new window felts interior and exterior. Brand new window runners and freshly lubed runners. I did service the regulator a few years back. Do these regulators wear out or bind over time? I included a video after install and a picture of the rocket installed for reference.
Thanks

I'm sure you'll get an official response soon but @Jwiech if you unplug the window rocket from the socket do your windows still work? If they do still work then you pulled/replaced a different relay from the one that controls the windows. If the windows stop working then you are in the correct socket and there may be another problem like the voltage step-up converter not increasing the voltage for some reason?
