EXT: Making Intermittent Wipers Variable Speed

[lucifer1]

After I got pm from fifedog229 who was having some issues with doing mod with a different version of the blue box, a better solution has been found. The 95 Accord v6 lx/ex 38600-SV7-A11 icu differs slightly from 96-97 Accord 38600-SV7-A12 I used. Luckily I pulled an extra box the last time I was at the junkyard and it happened to be an a11. After comparing and testing, the A11 has the corner light circuitry built in like the cb7. This allows the A11 to replace the accord icu and not have to piggyback 2 icus.

Tha A11 icu has the lights on buzzer built in so there no output to the external one. The internal light buzzer works when the icu is plugged in. The pin 3 orange output wire can be left in place since there is nothing connected on the board.

The A11 also has seat belt buzzer built in but is not needed for 90-91 since the auto seat belt module already does this. I don't have a 92-93 wiring diagram to see if the red/blu wire is present for the seat belt or if it needs to be run.

The key in buzzer has to be rewired. The cb7 has a 12v switched buzzer but the newer cars are ground switched. I wired up a relay inside the module to change it. I moved the the blu/wht key wire to the unused slot above it and soldered to the terminal to use as input to relay. I ran the relay output to the original key terminal and soldered it.

Add the variable wires to pin 6,7 and you are done. A whole lot easier than two icus.

Nice!!! I believe I just found my next mod.

deeve please move this to the DIY section ^_^

I've had no problems with the A11 and have gotten used to not having a key in chime. Also the stalk doesn't need to be modifed if you are putting it into a 92-93. I would have updated this a long time ago but I don't have enough posts. Thanks for sharing.

nice info ^^ i think not having the key chime would be a good thing ^__^

not for me lol

moved to diy's. nice write up. later.

Wow i had never seen this.

Props to OP.

Awesome DIY, and an awesome idea.

This is interesting. I have never seen this DIY before. Glad it was bumped and moved.

DIY sounded a bit confusing from reading.

I plan on tackling this if I ever go to a junkyard and find the parts.

Thanks again Lucifer! I did this mod last week and this is the results.






















So far Ive tested it while there is no rain or water lol. It works good so far

[Tippey764]

Of course the legend had this as standard lol. Its the most expensive car honda made besides the NSX

LS 5 speed legend? Now thats rare.

ya i have all my parts i just gotta figure out which pin on the white connector is ground for the ICU. when i pulled the whole interior fusebox out of the CD5 and CB7 the plug ins are in different configuration so i will have to test light it.

Hey, You dont have to swap out the entire fuse box panel... Just remove the ICU with a flat head from the fuse box panel thats original to the car.

So a11 ICU plugs right in to the CB fuse box panel... No need to do extra work and remove the entire fuse panel.

I just modified my 87 crx to give it variable intermittent wipers and figured a couple new things out. I now should be able to modify the stock cb7 brown icu to give it variable intermittent function.

I'm confused on how the key in buzzer is wired. I see on the pigtail to move the blu/wht wire to the slot above it, but now here are my next questions: what kind of relay do i need? and where on those "L" shaped pins do I solder the relay to? anywhere?

Also, what is the black wire coming out of the relay and going under the circuit board?



For the variable wires, which wire from the pigtail (pigtail wires on right) connects to which wire from the switch (switch wires on left)?


PIN 6 IS THE WHITE/LIGHT BLUE ONE ON THE RIGHT. PIN 7 IS THE RED/YELLOW ONE ON THE RIGHT

Thank you in advance for reading this post, and I hope to hear from someone soon about this question!

In the picture where I soldered internally is 4 and 13, for the relay to change the positive switching to negative for the key buzzer. I moved the terminal from 13 to unused slot 4. #4 connects to relay's 85 terminal, relays 86 and 87 are grounded, and relays 30 terminal connects to icu #13. The black wire is the ground which connects to on the other side of the board to the internal connector. I used a small 12v circuit board relay that fits inside the case.

You could also just put the relay external and cut the wire at pin 13, harness side goes to relay 85, icu side to relay 30, and 86,87 to ground.

It does not matter which wire from 6 and 7 connects to at the switch.
