UPDATE
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.
UPDATE
Being in California where it hardly rains, I typically use the intermittant wiper setting. Unfortunately it is one speed and not the speed you ever want. So I changed a few things around and added variable speed to the intermittant wipers.
Alot of Hondas come with the variable speed electroncis already in the vehicles whether it was ever offered or not. The 90-93 Accord is not one those lucky ones. The electronics for most are built into the ICU on older cars and the multiplex of newer of ones. Both of these are integrated into the fuse box. The older accords, civics,crv,prelude, cl use the ICU to control the intermittant function. The 95-97 accord ICU have variable function built into them. This module uses the same internal and external plug as the 90-93. Swap the ICU and you have variable capability. This comes at the expense of the control for corner blinkers which the newer model does not control and a built in chime vs exrternal chime. Rather than rewire the lights, I decided to just use 2 ICUs, the stock one and a newer one just controlling the wiper functions.
There are only 4 wires that go to back of the ICU for the wipers, these ae located in two seperate plugs at the back of the fusebox. I removed these wires from the connectors and ran them to a connector shell I had laying around. I also spliced into the ICU 12v power and ran a ground wire to the factory ground to power the 2nd ICU. Since the inputs to ICU are on the back and internal, I soldered wires directly onto the board so it could mount easier. Once all wired up the wipers will function just like before. To vary the speed of the in wipers, vary resistance on pin 6 an 7( of the green ICU side plug) between 0-30,000 ohm. This can be done with a simple potentiometer or a wiper switch with built in controls.

Since there are no variable wiper switches for a 90-93 it must come from another model. Since I have a 90, this will apply 90 and most likely 91. 92-93 have air bag and from what I can tell the larger combination switch holder. The switch I got is from a CL but also is found on the Accord and TL. The newer variable switch is larger, uses a different connector, and has a different stalk angle.
Upon disassembly, I found out the internals are the same. The stalk will fit into the smaller 90 shell use the 90 rear contact panel so no connector changes have to be made. Just add 2 new wires to the extra 2 pin connector for variable control.
This leaves the angle difference, being too close to the steering wheel. The stalk arm has a different angle on it and need to be modified. I filed down the end on the stalk arm allowing it to angle back to the 1990 position

Very nice work!
