Ok before I begin, I know that their is already plenty writeups on this but I've found most of them to be incomplete and only cover the actual installation o the wheel.
In this write up, I intend to give you as complete guidelines as possible to remove the stock steering wheel, install the new hub, quick release, and steering wheel, wire the horn, jump your srs system so that your other airbags still work, and how to relocate your cruise control.
Disclaimer:
Now remember this is only a guide and I nor the owners of this site assume responsibilty for any injuries or damages you do to yourself or your vehicle.
This write up is particular to the EM1 99-00 civic si, but can be used as a guide for other honda's.
Now that's out the way a few of the tools you will need to complete this project.
19mm socket and rachet
phillips screwdriver
T30 Torx driver, they come as torx bits and torx sockets, I prefer the socket style, for those of you that don't know what they are, here's a pic
First thing you wanna do is make sure your wheels are straight. Once that's done turn off you vehicle and lock the wheel so it stays straight. Next disconnect your battery, both cables ( I only disconnected the neg. cable and everything still turned out fine), but the manual says to do both. Wait at least 3 minutes to let the power drain from the vehicle. Make sure you have the security code for our radio before disconnecting the battery if applicable.
Next there are 2 tabs, 1 on either side of the steering wheel that needs to be removed, pictued below are the locations
Right Side
Left Side
Now you remove the 2 torx screws, 1 on either side of the wheel, torx screw is pictured above and circled in blue.
Now you remove the cruise control switch if equipped that's on the right side of the wheel. It's bolted in place via 2 phillip screws.
Pic upon removal
Once those are out unclip the connector tabs attached to the unit then you can just pull off the airbag portion of the wheel, be care not to drop hit or handle it roughly. Now you should be looking at an image like this.
Now grab your ratchet and 19mm socket and unscrew the nut in the center of the wheel, once this is off you can just pull off the wheel, if it's not coming off pull down the tilt adjustment lever s you can move the steering column up and down to get it in the right position that will allow the wheel to come off. Now you should be looking at something like this
and if you have airbags this SRS reel will be on there as well
Now I've seen a prelude that had a momo hub that had enough space to leave the reel in place, however my hub would not allow this so remove the reel by removing the 3 phillip screws holding it in place and also unlatching the yellow connector which you will find if you just follow the wires from the wheel to under the dash, I didn't know this at the time and just ended up cutting the wires, The connector has a spring loaded latch that you just pull back and the other half pops out, the half that you pull back looks like this
Ok now you're ready to put on your new hub and quick release. Now the easist way os to find the dots/indentations on the hub and quick release.They mean up or top. Now while the hub itself doesn't have to be in the top position the release does need to be straight, that is if you want your steering wheel to be straight when you put it on. Now you use the 19mm nut that you took off earlier to bolt your new hub in place, then attach the quick release making sure to attach the wires from the hub to the quick release before bolting it down. NOw it should look like this
Now for the horn:
There's a black female connector with 3 wires, Get a wire tap and a short piece of wire and tap into the mustard color wire. If you don't have this color wire, just grab a multi meter and locate the wire that's giving off 12v, there should only be one wire giving off any readings.
Grab your steering wheel and unscrew this metal tab.
or you can come up with your own way to get the hot wire to make connection to the back of the hub. This is what I came up with and it was quite simple. Ok now screw the tab onto one of the post that you unscrewed your srs reel from. Hook up the hot wire to one end of the tab and bend the other end of the tab so that it makes constant contact with the back of the hub.
Ok now put your steering column covers back on cause you're done with the wheel and horn.
