Part 3
PART 3: Disassembly
That was the easy part. From here it gets a bit hairy
YOU WILL BE REMOVING YOUR STEERING WHEEL, AIRBAG AND MANY OTHER PARTS THAT WILL KEEP YOUR CAR FROM FUNCTIONING.
IF YOU PUT THEM BACK TOGETHER WRONG YOU ARE GOING TO HAVE PROBLEMS, TAKE YOUR TIME AND READ ALL THE DIRECTIONS TO SEE WHAT YOU ARE GETTING INTO HERE.
IF YOU ARE NOT COMFORTABLE SOLDERING, ESPECIALLY WHEN ADJACENT WIRES CONTROL YOUR AIRBAG, THEN DON'T GO ANY FURTHER.
ALTERNATIVES TO DOING IT MY WAY:
My method works, is there an easier way? most likely, is it as reliable? I don't know.
1) Read Professor Fate's CR-V mod:
He did it using existing wires in the steering column. There is a redundant wire for the horn, he clipped this and reused it for the remote. He later found that the ground in the steering wheel was insufficient and ended up soldering in the spool anyhow. Personally I'm not sure why the ground wouldn't be sufficient, the horn has to go to ground to work right?
2) Read another alternative routed through the cruise switches
I don't have the electrical knowledge required to build up something like this, besides the cruise switch is so inconvenient to get to that I never turn it off.
3) Buy a Honda Pilot spool.
I'd give it a 50/50 chance that you could buy a $35 SRS Spool for a Pilot and just swap the two. The spool has no circuitry, just wires. Only question is if the connectors are compatible. If you can swap them directly then you will save quite a bit of the work and a lot of the stuff that some people are going to have a very difficult time with.
Well I decided to save the $35 and go ahead and do the soldering.
Process:
Disconnect your Negative battery terminal!!! Yes I know most people tell you to do this even if you are changing your oil but seriously. You will be disconnecting your airbag and you don't want to take a trip to the dealer to reset your sensors. I also removed the gauge cluster and wasn't going to mess around.
You can remove as much or as little of the dash as you feel necessary, I took off the entire gauge cluster, center console trim ring, and fuse panel. If nothing else, you will keep these items from being damaged and make wire routing easier. Fold your back seats flat to stack your trim parts on and start disassembling.
eMass' Steering wheel removal instructions:
Dash panel removal :
CRCError Explains it well here
Steering column cover removal:
Remove the three screws holding on the lower steering column cover then release the tilt steering lock lever.
Carefully unclip the six clips holding the top and bottom halves together. I don't know a good way to get these apart, they seem to break easily and the top cover prevents you from pressing in to release them. This is the only part I broke in the whole project, so I'm okay with it. Release the tilt steering lock lever and pull the bottom trim cover off by pulling it out away from the ignition.
You're going to be left with something like this eviscerated mess (photo taken later so there are two extra wires)
Next you will want to completely remove the multi position switch/spool assembly by unhooking its harness.
(again the dash and wheel are already back on because these pictures didn't turn out and had to be reshot)
Unhook large gray connectors from right and left switches
Unhook small 5pin white connector from spool
Unhook lower yellow airbag connector and free the connector from the steering column by unclipping the white nylon clip (easier said than done, pliers or screwdrivers work best.
Remove the three screws holding on the switch/spool assembly. Their mounting points are indicated below:
If you've released all the necessary connectors and clips you should be able to take the assembly right out of the car
If you look at the back of the assembly You will see that the spool clips onto the multiswitches on the top and bottom. Release the top first by inserting a screwdriver in under the four green wires and where the 5pin connector came out of. Pry up on this gently to release the top tab. The bottom tab is easily accessed with a screwdriver as well. The spool is now separate and is easier to work on in a better lit, more comfortable, place.
